*** SECURITY REMINDER ***
You are browsing as root on an outdated kernel that is not likely to see timely security patches. You should at least create a non-root user (e.g. using adduser), but they would need permission to use the framebuffer i.e. FBInk, if they want to use the graphical image viewer feature. To create a user 'fbuser' with framebuffer access you can do the following: adduser fbuser addgroup fbgroup adduser fbuser fbgroup chgrp fbgroup /dev/fb0 But it looks like you have to redo that last chgrp command each session. Furthermore, Kobo seems to have disallowed write access to /mnt/onboard to anyone but root, so other users cannot save bookmarks to .elinks/ but they can at least save downloads to the /tmp directory (of course you then have to copy them as root to a more permanent location). *NOTE* You can edit the "umask 002" line in /etc/init.d/rcS to "umask 000" allow all user write access to the /mnt/onboard partition, but that would defeat the security objective. You can't have fine-grained access permission because it is a vfat format. When you create a user with "adduser bla", a /home/bla directory is created on the root partition, which DOES have fine-grained access controls, as you can see by running "ls -l /home". But the root partition doesn't have much free space, only about 60MB, as you can see by running "df". So you may prefer "adduser bla -d /mnt/onboard/.adds/koreader/home/bla" to put the home directory on the /mnt/onboard partition which has many GB of free space, which the user won't be able to write to, but at least it doesn't use up valuable root partition space. In retrospect I should have crosscompiled using "--prefix=/mnt/onboard/.adds/koreader/templib" on my desktop instead of "--prefix=$HOME/Downloads/mykobossh/templib", so I wouldn't have to use up valuable root partition space with all the certificates, as you will see. The links near the bottom of this post point to an alternative approach using a chroot. Clara HD owners also have the option to pull out the SD card and shrink the /mnt/onboard partition with a disk utility, then creating a new /home partition that is writable by non-root users. But non-Clara owners can still create a /home partition in an image file, as was done here, (but no need to create root file system - just format it and mount it.) **EDIT - Comment #3 has another way to get elinks by copying and may be easier. Otherwise: 1.Back up your SD card. 2.Don't use your Kobo for sensitive info including passwords. 3.Don't browse to unsafe sites. Or just use Firefox on your desktop to save complete webpage with image folder, or print to pdf on your cellphone, these can be webserved to your Kobo for secure graphic browsing using KOReader! As mentioned here *** HOW TO CROSSCOMPILE ELINKS AND WGET FOR THE KOBO CLARA HD (using linux desktop). --- First, follow the instructions here to determine the crosscompile tool for your device. For the Kobo Clara HD, it is gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf.tar.xz. Download this and source packages for openssl, elinks, and wget to $HOME/Downloads/mykobossh/. --- To build OPENSSL: (see also) cd cd Downloads/mykobossh/ tar xJf gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf.tar.xz export PATH=$PWD/gcc-linaro-7.3.1-2018.05-x86_64_arm-linux-gnueabihf/bin:$PATH tar zxvf openssl-1.1.1s.tar.gz cd openssl-1.1.1s/ mkdir $HOME/Downloads/mykobossh/templib ./Configure gcc -static -no-shared --prefix=$HOME/Downloads/mykobossh/templib --cross-compile-prefix=arm-linux-gnueabihf- make make install cd .. --- To build ELINKS: (see also) tar zxvf elinks-0.15.1.tar.gz cd elinks-0.15.1/ ./autogen.sh ./configure --help ./configure --host=arm-linux-gnueabihf --enable-own-libc --enable-sm-scripting --disable-nls --disable-xbel --disable-ipv6 --disable-leds --disable-backtrace --with-static --without-zlib --without-bzlib --without-gnutls --with-openssl=$HOME/Downloads/mykobossh/templib CPPFLAGS="-I$HOME/Downloads/mykobossh/templib/include" LDFLAGS="-L$HOME/Downloads/mykobossh/templib/lib" make cp src/elinks ../elinks111s cd .. --- DEVICE: Copy elinks111s to .adds/koreader/scripts directory on Kobo Clara HD. Run KOReader and connect to WIFI on Clara HD. Open Terminal Emulator and you will see elinks111s in working directory (/mnt/onboard/.adds/koreader/scripts). chmod +x elinks111s elinks111s (enter "mobileread.mobi/forums/") (keep pressing return key if get ssl error message) ***EDIT*** It helps to copy certificates to a $HOME/Downloads/mykobossh/templib/ssl/certs directory that you must create on your Kobo, where $HOME is /home/user, or whatever your desktop home directory was. I got certificates from my desktop /usr/share/ca-certificates/mozilla directory, but your case may differ. Also, a heavy page like amazon might stall, but I press q then cancel and it seems to get going again! *Update-wget seems to handle certs differently. A workaround might be to copy the ca-certificates.crt file from your desktop (mine was in /etc/ssl/certs) to the above directory, and let wget know by creating a .wgetrc file in /mnt/onboard/.adds/koreader with the single line: ca_certificate=/home/user/Downloads/mykobossh/templib/ssl/certs/ca-certificates.crt (or wherever you saved it). ** Update-Courtesy of qkqw's post, here is another source of Mozilla CA certificates from the Curl website. *** Press Esc key and down arrow key to get menu and key codes. Use spacebar for pagedown and 'b' for pageup, 'g' followed by '.' to browse local filesystem. Press q (followed by return key) to quit --- NiLuJe's FBInk can be configured as an image viewer for elinks, except the image gets quickly overwritten. But it is there long enough to decide if you want to download it. Turns out I had to not use the FBInk that came with my installed KOReader but to download it separately from here. EDIT elinks.conf FILE IN .elinks/ (TO CONFIGURE fbink AS IMAGE VIEWER): set document.browse.images.display_style = 1 set document.browse.images.filename_maxlen = 50 set document.browse.images.image_link_tagging = 2 set document.browse.images.show_as_links = 1 set mime.extension.jpg="image/jpeg" set mime.extension.jpeg="image/jpeg" set mime.extension.png="image/png" set mime.extension.gif="image/gif" set mime.extension.bmp="image/bmp" set mime.extension.pnm="image/pnm" set mime.handler.image_viewer.unix.ask = 1 set mime.handler.image_viewer.unix-xwin.ask = 0 set mime.handler.image_viewer.unix.block = 1 set mime.handler.image_viewer.unix-xwin.block = 0 set mime.handler.image_viewer.unix.program = "/mnt/onboard/.adds/koreader/scripts/fbink -g file=%" set mime.handler.image_viewer.unix-xwin.program = "/mnt/onboard/.adds/koreader/scripts/fbink -g file=%" set mime.type.image.jpg = "image_viewer" set mime.type.image.jpeg = "image_viewer" set mime.type.image.png = "image_viewer" set mime.type.image.gif = "image_viewer" set mime.type.image.bmp = "image_viewer" set mime.type.image.pnm = "image_viewer" --- *EDIT* Actually "fbink -G -g file=% ;sleep 2" keeps the image longer. I tried appending 2>/dev/null but that only helps outside of elinks. *You need that space between "%" and ";" for some reason. Another option is: "fbink -G -y 30 -g file=% ;sleep 2" Which keeps the image to the lower part of the display, so it doesn't get overwritten. --- To build WGET: (see also) tar zxvf wget-1.21.tar.gz cd wget-1.21/ ./configure --help env CPPFLAGS="-I$HOME/Downloads/mykobossh/templib/include" LDFLAGS="-L$HOME/Downloads/mykobossh/templib/lib" ./configure --with-ssl=openssl --with-libssl-prefix=$HOME/Downloads/mykobossh/templib --target=arm-linux-gnueabihf --host=arm-linux-gnueabihf --disable-nls --disable-ipv6 --without-zlib make CPPFLAGS="-I$HOME/Downloads/mykobossh/templib/include" LDFLAGS="-L/$HOME/Downloads/mykobossh/templib/lib -static" cp src/wget ../wget111s DEVICE: Copy wget111s to .adds/koreader/scripts directory on Kobo Clara HD. Run KOReader and connect to WIFI on Clara HD. Open Terminal Emulator and you will see wget111s in working directory (/mnt/onboard/.adds/koreader/scripts). chmod +x wget111s wget111s google.com ls index.html Here is a more sophisticated use: ***NOTE THE VERY IMPORTANT OPTION '-Q50M' WHICH LIMITS DOWNLOAD TO 50MB !!!*** (this is to keep you from inadvertently "downloading the internet") wget111s --no-check-certificate --no-parent -k -nd -D www.mobileread.mobi -E -r -A jpg,jpeg,png,gif,htm.html -l1 -Q50M -P ./mywgets/ www.mobileread.mobi/forums/ ------ THE NEXT SECTIONS ARE OPTIONAL, IF YOU WANT AN ASCIIVIEW IMAGE VIEWER. *It is for ascii images - not high resolution images, from when I could not get NiLuJe's FBInk to work within elinks. So this is mostly just a fun substitute! Spoiler:
Finally, if you have gotten this far and said, whew, that was a lot, then "HOWTO Create your own native development environment on your Kobo!" might be making a lot more sense now! *EDIT:Looks like graphical browser with Xorg is also available via chroot. Extra Clara HD config steps on post #46.. So there you have an almost graphical browser. *Actually, if you use wget (the real one you compiled above, or maybe the cURL binary installed from NiLuJe's kobostuff package - not the stripped-down one that comes with KOReader) you can with a little practice download a page WITH images and that can be opened WITH IMAGES(if they are local, like saved as complete webpage by Firefox) in KOReader for a graphical view!

***TO DOWNLOAD "COMPLETE" WEB PAGE (Firefox-style)***
Follow instructions at this link to add uri passing to our cross-compiled wget111s command from above, except name the entry "wgets", use the command "wget111s --no-check-certificate --show-progress -nd -E -k -p -Q20M %c", and assign keybinding "Ctrl-W". Press ENTER key and save by tabbing to the "SAVE" button and pressing ENTER, then ESC to get back to current page. Now, if you press g, then "g" for google, followed by ENTER, elinks will take you to the google search page. Enter "Ctl-w" and complete web page is saved to current directory. To verify, press g, then "." for current local directory, followed by ENTER, then maybe "Ctrl-r" to refresh cache, and a few down-arrow presses to scroll, and voila, your complete web page with images! Now if you want to browse this page in the luxury of the KOReader environment, turn off networking to be sure you are looking at locally saved files, and browse to your download directory in KOReader to see the "complete" web page with images displayed. *Note-this option was done while running elinks111s as root, so that the change would be written to the elinks.conf file. *LONG INSTRUCTIONS FROM LINK: Spoiler:

***PLS SEE SECURITY REMINDER ON TOP POST***
COPYING ELINKS BINARY TO KOBO CLARA HD WITHOUT COMPILING OR CHROOT: (Some may find this an easier way to get the elinks browser.) You can see dependencies of elinks from here. Depends (6) libbz2 libcrypto3 libexpat libssl3 musl zlib You can get the packages from here. You can get a CA certificate store from here. DOWNLOAD THE REQUIRED PACKAGES: $ wget https://dl-cdn.alpinelinux.org/alpin...-0.15.1-r1.apk $ wget https://dl-cdn.alpinelinux.org/alpin...2-1.0.8-r4.apk $ wget https://dl-cdn.alpinelinux.org/alpin...3-3.0.8-r1.apk $ wget https://dl-cdn.alpinelinux.org/alpin...t-2.5.0-r0.apk $ wget https://dl-cdn.alpinelinux.org/alpin...3-3.0.8-r1.apk $ wget https://dl-cdn.alpinelinux.org/alpin...l-1.2.3-r4.apk $ wget https://dl-cdn.alpinelinux.org/alpin...-1.2.13-r0.apk $ wget https://curl.se/ca/cacert.pem RUN THESE COMMANDS FROM LINUX DESKTOP OR ENVIRONMENT(really just need to unarchive and copy some files, but the tar command fails if you try it on the vfat filesystem /mnt/onboard of the Kobo because of vfat not supporting symlinks.

Copy your elinks binary from the scripts/ folder on the PC to the /mnt/onboard/.adds/koreader/scripts/ folder on the kobo. Note the contents of /mnt/onboard/.adds/koreader/libs/ already has a libz.so.1 lib. Copy all libs except libz.so.1 from the libs/ folder on the PC to the /mnt/onboard/.adds/koreader/libs/ folder on the kobo. Note that these new libs all have a different date than the default pre-existing libs. Copy your cert.pm and certs/ca-certificates.crt to the /etc/ssl/ directory.(You may notice there is already one in the /mnt/onboard/.adds/koreader/data/ folder anyway.) RUN THESE COMMANDS IN KOREADER TERMINAL, OR FROM A TELNET/SSH CLIENT CONNECTION: ***SECURITY REMINDER*** Telnet sessions are in cleartext INCLUDING LOGIN SESSIONS, so only use on a private network, if at all! If you always have DEVMODE set to ON for whatever reasons , that means Telnet is on by default, unless you toggle it off , e.g. using NickelMenu. You can install KOReader to get the more secure SSH option, and NiLuJe's kobostuff provides a package that includes an SSH binary. You can start the KOReader SSH server via NickelMenu. ********************************** IF RUNNING FROM KOREADER TERMINAL: # elinks IF RUNNING FROM A TELNET/SSH CLIENT CONNECTION: # cd /mnt/onboard/.adds/koreader/ # export LD_LIBRARY_PATH=/mnt/onboard/.adds/koreader/libs/ # echo $LD_LIBRARY_PATH # ./scripts/elinks You then enter '.' to see current working directory, or enter a web address (just keep pressing return if you get SSL errors).

But if you download packages from the edge branch, as was the case for moon-buggy, its dependencies will keep changing as the rolling edge branch keeps updating. So at some point the provided links will be out of date, and you would have to search for the package yourself in the edge branch or the latest branch(e.g. 3.18): https://pkgs.alpinelinux.org/packages?arch=armv7 This would list the up-to-date dependencies.

There was a framebuffer-based terminal emulator that runs on the Clara HD (you have to compile it), which you can control from your phone or PC keyboard: https://www.mobileread.com/forums/sh...d.php?t=298877 These are the build directions if you have a couple of hours to kill (binary attached for your convenience.) *** On a debian PC: koreader/koxtoolchain https://github.com/koreader/koxtoolchain $ git clone https://github.com/koreader/koxtoolchain.git $ cd koxtoolchain/ $ sudo apt-get install build-essential autoconf automake bison flex gawk libtool libtool-bin libncurses-dev curl file git gperf help2man texinfo unzip wget $ ./gen-tc.sh kobo (2 hours build time on an Acer Chromebook 11 converted to an MX Linux workstation) $ cd .. *** $ mkdir fbpad-build $ cd fbpad-build/ JulianDroske/fbpads https://github.com/JulianDroske/fbpads forked from aligrudi/fbpad $ wget https://github.com/JulianDroske/fbpa...ads/master.zip $ unzip fbpads-master.zip $ cd fbpads-master/ $ make $ cd fbpad_mkfn/ $ make $ nano -l gen.sh 5 OP="-h34 -w19" 6 SZ="18h135v135" 7 # OP="-h26 -w14" 8 # SZ="18h100v100" $ ./gen.sh $ cd .. $ cd .. *** NiLuJe/FBInk https://github.com/NiLuJe/FBInk/releases $ wget https://github.com/NiLuJe/FBInk/rele...v1.25.0.tar.xz $ tar xJf FBInk-v1.25.0.tar.xz $ cd FBInk-v1.25.0/ $ source ~/koxtoolchain/refs/x-compile.sh kobo env bare $ make static stripped $ cd .. ddvk / fbpad-eink forked from kisonecat/fbpad-eink https://github.com/ddvk/fbpad-eink $ wget https://github.com/ddvk/fbpad-eink/a...ads/master.zip $ unzip fbpad-eink-master.zip $ cd fbpad-eink-master/ $ cp -r ../FBInk-v1.25.0/Release FBInk/ $ cp ../FBInk-v1.25.0/fbink.h FBInk/ $ cp ../fbpads-master/fbpad_mkfn/ar.tf fonts/ $ cp ../fbpads-master/fbpad_mkfn/ai.tf fonts/ $ cp ../fbpads-master/fbpad_mkfn/ab.tf fonts/ $ nano -l conf.h 17 typedef int fbval_t; ... 20 #define FR "ab.tf" 21 #define FI "ab.tf" 22 #define FB "ab.tf" $ nano -l Makefile 3 CC := arm-kobo-linux-gnueabihf-gcc ... 10 xxd -i fonts/ab.tf > font.h $ nano -l font.c 40 memcpy(&head, fonts_ab_tf, sizeof(head)); ... 46 font->glyphs = (int*)(fonts_ab_tf + sizeof(head)); 47 font->data =(char*) (fonts_ab_tf + sizeof(head) + font->n * sizeof(int)); $ xxd -i fonts/ab.tf > font.h $ make $ file fbpad fbpad: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.33, with debug_info, not stripped $ cd .. *** Copy the fbpad binary to the /mnt/onboard/.adds/koreader/scripts/ directory on your Kobo.

(Try elinks if you have good eyesight.)UPDATE- Fixed font size - now very readable. Hit the lower right corner of the screen and the nickel menu comes up. Ctl-Alt-q to quit If that doesn't work, try "pkill fbpad". *** How about let's change the default elinks keybindings to allow normal use of arrow keys: The hard way (see below for the easier way): In elinks, press 'k' to bring up Keybinding manager. Press Space to expand [+]- Main mapping. Use Right arrow to move focus to Delete tab. Use Down arrow to scroll to and delete the following: [-]- Move to the next frame: Tab [-]- Move to the previous frame: Shift-Tab [-]- Return to the previous document in history: Left [-]- Go forward in history: u [-]- Follow the current link: Right [-]- Follow the current link, forcing reload...: Ctrl-Right [-]- Open a lua Console: , [-]- Move to the next link: Down [-]- Move to the previous link: Up [-]- Move downwards by a page: Ctrl-F [-]- Move upwards by a page: Ctrl-B [-]- Search link text by typing ahead: # [-]- Toggle displaying of links numbers: . Use Right arrow to move focus to Save tab. Save and Close. Press 'k' to bring up Keybinding manager again. Press Space to expand [+]- Main mapping, or Up arrow to scroll to the top if already expanded. Use Left/Right arrow to focus on Add tab. Use Down arrow to scroll to and add the following: [-]- Move to the next frame: Ctrl-f [-]- Move to the previous frame: Ctrl-b [-]- Return to the previous document in history: , [-]- Go forward in history: . [-]- Show information about current link: u [-]- Open a lua Console: Alt-l [-]- Move cursor down: Down [-]- Move cursor left: Left [-]- Move cursor right: Right [-]- Move cursor up: Up [-]- Move to the next link: Tab [-]- Move to the previous link: Shift-Tab [-]- Toggle displaying of links numbers: # Use Right arrow to move focus to Save tab. Save and Close. The easier way: Or you could just append to the end of the config file: $ vi .elinks/elinks.conf Code:
################################## # Automatically saved keybindings # bind "main" "Ctrl-F" = "frame-next" bind "main" "Ctrl-B" = "frame-prev" bind "main" "," = "history-move-back" bind "main" "." = "history-move-forward" bind "main" "u" = "link-info" bind "main" "Alt-l" = "lua-console" bind "main" "Down" = "move-cursor-down" bind "main" "Left" = "move-cursor-left" bind "main" "Right" = "move-cursor-right" bind "main" "Up" = "move-cursor-up" bind "main" "Tab" = "move-link-next" bind "main" "Shift-Tab" = "move-link-prev" bind "main" "#" = "toggle-numbered-links" bind "main" "Ctrl-Right" = "none" So the new way of navigating in elinks would be: On startup, enter '.' to see current working directory, or enter a web address. Tab and Shift-Tab to traverse the links. Enter to follow link or '.' and ',' to go forward and back. Space and 'b' to page forward and back. '[' and ']' to go left and right. Enter to edit a text field, 'd' to download link. 'a' to add a bookmark, 's' to see them, TAB to move through options. ESC followed by Down arrow and Left/Right arrows to see menus. 'g' to enter a new address, 'q' to quit. Main difference being now able to move around the page with arrows keys. Old Down/Up link travelling replaced by Tab/Shift-Tab, and old Left/Right history traversing replaced by ','/'.'. *** Also get rid of the colors in the ls command by appending this to the /korenv.sh file: # vi /korenv.sh Code:
#!/bin/sh export PATH=$PATH:/mnt/onboard/.adds/koreader/scripts:/mnt/onboard/.adds/koreader/plugins/terminal.k export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mnt/onboard/.adds/koreader/libs export TERM=xterm export HOME=/mnt/onboard/.adds/koreader/ cd $HOME alias ls='ls --color=never' But it seems you have to run it again after running fbpad. *** To get rid of the colors in the w3m browser: In w3m, normally press 'o' to bring up the Option Setting Panel. Scroll down to the second group, Color Settings. Put the cursor on the first entry: Display with color. Tab to the ()NO option and press enter. Scroll to the end of the section, tab to the [OK], and press enter. Or just edit the config file: $ nano -l .w3m/config 38 color 0 But w3m doesn't handle very well fbpad with large font/low number of columns. Or at all, as you can see with the small-font "fbpads" that I reuploaded. Note: the "fbpads" I uploaded means "fbpad with Small font", not because it is the above JulianDroske/fbpads that I exploited earlier in the post for its font setup. Sorry for any confusion. *** Networking note: In Quitting Telnet Habit , I said that I wanted to quit telnet and turn off devmode ( Go to the Discover tab and search the store for "devmodeoff"). meaning I lost the "ForceWifiOn=true" option in [DeveloperSettings] in the /mnt/onboard/.kobo/Kobo/Kobo eReader.conf file. Unfortunately I now find the WiFi connection cutting out. Others have said leaving the Wifi applet dialog open helps, so I am trying that. *** Here's one with keyboard: NiLuJe/inkvt forked from llandsmeer/inkvt https://github.com/NiLuJe/inkvt $ mkdir inkpad-build $ cd inkpad-build/ $ wget http://http.us.debian.org/debian/poo....1.1-1_all.deb $ sudo dpkg -i libcxxopts-dev_3.1.1-1_all.deb OR $ sudo apt install libcxxopts-dev $ source ~/koxtoolchain/refs/x-compile.sh kobo env bare $ cp ../fbpad-build/FBInk-v1.25.0.tar.xz . $ tar xJf FBInk-v1.25.0.tar.xz $ wget https://github.com/NiLuJe/inkvt/arch...ads/master.zip $ unzip master.zip $ mv master.zip inkvt-master.zip $ cd inkvt-master/ $ mv ../FBInk-v1.25.0/* FBInk/ $ mkdir cxxopts/include $ cp /usr/include/cxxopts.hpp cxxopts/include/ $ make release Extract InkVT-.zip to Kobo.

Fbpad & USB
It seems there is somewhat flaky support for USB keyboard for fbpad on the Kobo, if you have some productive time to fritter away...
* requires USB host support: https://www.mobileread.com/forums/sh...d.php?t=340418 DOWNLOAD THE AGETTY PACKAGE: $ cd myalpine/ $ wget https://dl-cdn.alpinelinux.org/alpin...-2.38.1-r1.apk RUN THESE COMMANDS FROM LINUX DESKTOP: $ tar zxvf agetty-2.38.1-r1.apk $ mv sbin/agetty scripts/ NOW CONNECT YOUR KOBO TO YOUR PC: Copy your agetty binary from the scripts/ folder on the PC to the sbin/ folder on the kobo. Edit system file on your Kobo at your own risk (may blow up your device - just kidding, but type carefully) : EDIT /sbin/kobo_getty.sh Code:
#!/bin/sh [ -e /dev/ttymxc0 ] && /sbin/getty -L ttymxc0 115200 vt100 & [ -e /dev/ttyS0 ] && /sbin/getty -L ttyS0 0 vt100 & [ -e /dev/tty1 ] && /sbin/agetty -s 38400 -t 600 tty1 vt100 If I may paraphrase NiLuJe, "Here Be Dragons", where "Dragons" be a metaphor for messing up core system functionality possibly leading to failure to startup or connect, or even mysterious application malfunctions that manifest later on. These system files were put there by folks with comprehensive system level understanding, to be modified by folks who have invested many person-hours code-grokking/reverse engineering to achieve comparable understanding. Since I am neither, what is my excuse? Well on my Clara HD the first two lines are exactly the same except I added the "&" at the end. I then added the third line which I have researched the meaning of. Also I have multiple backups and contingency plans for connecting to and/or re-establishing my Clara. Also, it only cost 99 US$, is not used for work, and contains no important data. So non-expert readers, please make your own risk assessment. Edit NickelMenu config file: EDIT /mnt/onboard/.adds/nm/config.txt Code:
menu_item :main :fbpad :cmd_spawn :quiet:/mnt/onboard/.adds/koreader/scripts/fbpad /bin/sh 0</dev/tty1
chain_success :dbg_toast :Started fbpad
chain_failure :dbg_toast :Error
menu_item :main :Stop fbpad :cmd_spawn :quiet:/usr/bin/pkill fbpad
chain_success :dbg_toast :Stopped fbpad
chain_failure :dbg_toast :Error
Power off your Kobo. When you restart it, set USB host mode, plug in your powered USB connected keyboard, run fbpad from NickelMenu, and type (may stall). ***** CORRECTION FOR MORE STABLE OPERATION: DO NOT EDIT /sbin/kobo_getty.sh. RETURN IT TO ORIGINAL STATE, e.g.: Code:
#!/bin/sh [ -e /dev/ttymxc0 ] && /sbin/getty -L ttymxc0 115200 vt100 [ -e /dev/ttyS0 ] && /sbin/getty -L ttyS0 0 vt100 #[ -e /dev/tty1 ] && /sbin/agetty -s 38400 -t 600 tty1 vt100 INSTEAD EDIT /etc/inittab to add the agetty line only: Code:
::sysinit:/etc/init.d/rcS ::respawn:/sbin/kobo_getty.sh ::once:/sbin/agetty -s 38400 -t 600 tty1 vt100 ::ctrlaltdel:/sbin/reboot ::shutdown:/etc/init.d/rcK ::restart:/sbin/init ***UPDATE*** See POST #7 for a better way of doing this. *** Edit NickelMenu config file to add Stop agetty command: EDIT /mnt/onboard/.adds/nm/config.txt Code:
menu_item :main :fbpad :cmd_spawn :quiet:/mnt/onboard/.adds/koreader/scripts/fbpad /bin/sh 0</dev/tty1
chain_success :dbg_toast :Started fbpad
chain_failure :dbg_toast :Error
menu_item :main :Stop fbpad :cmd_spawn :quiet:/usr/bin/pkill fbpad
chain_success :dbg_toast :Stopped fbpad
chain_failure :dbg_toast :Error
menu_item :main :Stop agetty :cmd_spawn :quiet:/usr/bin/pkill agetty
chain_success :dbg_toast :Stopped agetty
chain_failure :dbg_toast :Error
Power off your Kobo. When you restart it, set USB host mode, plug in your powered USB connected keyboard, run Stop agetty, then fbpad from NickelMenu, and type (shouldn't stall). Last edited by elinkser; 09-15-2023 at 09:24 PM. Reason: risk notice, cd, corrected stability,better hack |

OSCREEN KEYBOARD
MAKING AN ONSCREEN KEYBOARD FOR OUR TERMINAL:
Fbkeyboard is a framebuffer keyboard that we can port to Kobo's fbink library, following the fbpad-eink example. $ mkdir fbkeyboard-build $ cd fbkeyboard-build/ *** First we build fbpad as in the previous post, except we leave some rows empty at the bottom of the screen for the keyboard. Assuming you have already built KOReader's koxtoolchain, NiLuJe's FBInk library, and Aligrudi/Droske's fbpads as before: $ source ~/koxtoolchain/refs/x-compile.sh kobo env bare $ unzip fbpad-eink-master.zip $ cd fbpad-eink-master/ $ cp -r ../FBInk-v1.25.0/Release FBInk/ $ cp ../FBInk-v1.25.0/fbink.h FBInk/ (First make fbpadkbS, the small font version of fbpad for onscreen keyboard.) $ nano -l conf.h Code:
17 typedef int fbval_t; Code:
3 CC := arm-kobo-linux-gnueabihf-gcc 4 all: fbpadkbS ... 11 fbpadkbS: fbpad.o term.o pad.o draw.o font.o isdw.o scrsnap.o FBInk/Release/libfbink.a ... 15 rm -f *.o fbpadkbS Code:
25 rows = fb_rows() * 29 / 51 / fnrows; Copy the fbpadkbS binary to the /mnt/onboard/.adds/koreader/scripts/ folder on your Kobo. (Now make fbpadkb, the large font version of fbpad for onscreen keyboard.) $ cp ../fbpads-master/fbpad_mkfn/ar.tf fonts/ $ cp ../fbpads-master/fbpad_mkfn/ai.tf fonts/ $ cp ../fbpads-master/fbpad_mkfn/ab.tf fonts/ $ nano -l conf.h Code:
20 #define FR "ab.tf" 21 #define FI "ab.tf" 22 #define FB "ab.tf" Code:
4 all: fbpadkb 10 xxd -i fonts/ab.tf > font.h 11 fbpadkb: fbpad.o term.o pad.o draw.o font.o isdw.o scrsnap.o FBInk/Release/libfbink.a ... 15 rm -f *.o fbpadkb Code:
40 memcpy(&head, fonts_ab_tf, sizeof(head)); ... 46 font->glyphs = (int*)(fonts_ab_tf + sizeof(head)); 47 font->data =(char*) (fonts_ab_tf + sizeof(head) + font->n * sizeof(int)); $ nano -l pad.c Code:
25 rows = fb_rows() * 25 / 42 / fnrows; Copy the fbpadkb binary to the /mnt/onboard/.adds/koreader/scripts/ folder on your Kobo. $ cd .. Add the following entries to /mnt/onboard/.adds/nm/config.txt: Code:

From MyBooks, go to the Activity page on your Kobo (second tab from left at bottom of screen.) From NickelMenu select Stop Agetty, fbpadkb, and fbkeyboard entries. (i.e. requires that you implemented the USB keyboard hack of the previous post.) Unfortunately too slow for practical use right now. Hopefully something can be tweaked to optimize it. Can exit with Stop fbkeyboard and Stop fbpadkb entries. *** EDIT: Added arrow keys to lines 39, 40 and 54 of fbkeyboard.c: Code:
38 char *special[][7] = {
39 { "Esc", "Tab", " ^ ", " v ", " < ", " > ", ">>⇓" },
40 { "Esc", "Tab", " ^ ", " v ", " < ", " > ", ">>⇓" },

53 __u16 keys[][26] = {
54 { KEY_ESC, KEY_TAB, KEY_UP, KEY_DOWN, KEY_LEFT, KEY_RIGHT, KEY_PAGEDOWN },

SAVING SPACE IN NICKELMENU WITH "SUBMENUS" USING NICKELDBUS
***
SAVING SPACE IN NICKELMENU WITH "SUBMENUS" USING NICKELDBUS Your NickelMenu might be getting crowded if you have added all the following entries: Code:
menu_item :main :stop agetty+fbpad+fbkeyboard :cmd_spawn :quiet:/usr/bin/pkill agetty
chain_success :cmd_spawn :quiet :/usr/bin/pkill fbpad
chain_failure :cmd_spawn :quiet :/usr/bin/pkill fbpad
chain_success :cmd_spawn :quiet :/usr/bin/pkill fbkeyboard
chain_failure :cmd_spawn :quiet :/usr/bin/pkill fbkeyboard
menu_item :main :fbpadkb+fbkeyboard :cmd_spawn :quiet :/mnt/onboard/.adds/koreader/scripts/fbpadkb /bin/sh 0</dev/tty1
chain_success :cmd_spawn :quiet :/mnt/onboard/.adds/koreader/scripts/fbkeyboard
chain_success :dbg_toast :Started fbpadkb and fbkeyboard
chain_failure :dbg_toast :Error starting fbpadkb or fbkeyboard
menu_item :main :fbpadkbS+fbkeyboard :cmd_spawn :quiet :/mnt/onboard/.adds/koreader/scripts/fbpadkbS /bin/sh 0</dev/tty1
chain_success :cmd_spawn :quiet :/mnt/onboard/.adds/koreader/scripts/fbkeyboard
chain_success :dbg_toast :Started fbpadkbS and fbkeyboard
chain_failure :dbg_toast :Error starting fbpadkbS or fbkeyboard
menu_item :main :fbpad (toggle):cmd_output :500:quiet :/usr/bin/pkill -f "fbpad"
chain_success:skip:4
chain_failure :cmd_spawn :quiet :/mnt/onboard/.adds/koreader/scripts/fbpad /bin/sh 0</dev/tty1
chain_success :dbg_toast :Started fbpad
chain_failure :dbg_toast :Error starting fbpad
chain_always:skip:-1
chain_success :dbg_toast :Stopped fbpad
menu_item :main :fbpadS (toggle):cmd_output :500:quiet :/usr/bin/pkill -f "fbpadS"
chain_success:skip:4
chain_failure :cmd_spawn :quiet :/mnt/onboard/.adds/koreader/scripts/fbpadS /bin/sh 0</dev/tty1
chain_success :dbg_toast :Started fbpadS
chain_failure :dbg_toast :Error starting fbpadS

chain_success :dbg_toast :Started fbkeyboard
chain_failure :dbg_toast :Error starting fbkeyboard
chain_always:skip:-1
chain_success :dbg_toast :Stopped fbkeyboard
*** But NickelDBus allows us to condense everything to a single NickelMenu entry (i.e. also need NickelDBus installed): Code:
menu_item :main :fbmenu :cmd_spawn :quiet:exec /mnt/onboard/.adds/koreader/scripts/fbmenu.sh
chain_success :dbg_toast :Started fbmenu
chain_failure :dbg_toast :Error
Also create script /mnt/onboard/.adds/koreader/scripts/fbmenu.sh: Code:
#!/bin/sh
# fbmenu - fbpad and fbkeyboard selection menu

qndb -m dlgConfirmCreate true
qndb -m dlgConfirmSetTitle "1-Stop agetty+fb(all); 2-fbpadkb; 3-fbpadkbS; 4-fbpad; 5-fbpadS; 6-fbkeyboard; Select option (1-6):"

*** A NEW HACK TO AVOID MESSING WITH SYSTEM FILES LIKE A PRO: * While messing around with an rmkit install, I saw how they avoided messing with system files like we did in POST #5 above: Return your /etc/inittab to to the way it was (i.e. remove the "agetty" line you added). Instead create the following file: /etc/udev/rules.d/90-fbpad.rules Code:
# : 90-fbpad.rules 2015-01-10 23:58:00Z NiLuJe $ # Runs early at boot... (onboard *might* be mounted at that point) KERNEL=="loop0", RUN+="/sbin/agetty -s 38400 tty1 vt100" It would be nice if we could also kill agetty automatically with the following file, but I tried it and that one doesn't work: /etc/udev/rules.d/91-fbpad.rules Code:
# : 91-fbpad.rules 2015-01-10 23:58:00Z NiLuJe $ # Runs early at boot... (onboard *might* be mounted at that point) KERNEL=="loop0", RUN+="/usr/bin/pkill agetty" *** IMPORTANT NOTE: ON MY KOBO, EITHER USB OR WIFI NETWORKING (WHETHER CONNECTED TO HOTSPOT OR NOT) HAD TO BE ENABLED OR DEVICE FREEZES. WHO KNOWS WHY? SORRY FOR ANY FRUSTRATION - I HAD DONE MANY SUCCESFUL TESTS NOT REALIZING THAT ENABLING WIFI WAS RELEVANT! **** Last edited by elinkser; 09-16-2023 at 07:27 PM.

ADD A CHESS GAME FOR THE TERMINAL
***ADD A CHESS GAME FOR THE TERMINAL***
Here's a chess app to stress test your fbpadkb, and have a little fun at the same time! The gnuchess game has only the following dependencies: Depends (3) libgcc** libintl musl* * Already got it from the Elinks/Nano install above (POST #3 - also got the /korenv.sh script.) ** Do not install libgcc since it would crash OCP-KOReader-v2023.06 when opening pdf files. Fortunately, gnuchess runs fine without it! RUN THESE COMMANDS FROM LINUX DESKTOP: $ cd myalpine/ DOWNLOAD THE REQUIRED PACKAGES: $ wget https://dl-cdn.alpinelinux.org/alpin...s-6.2.9-r1.apk $ wget https://dl-cdn.alpinelinux.org/alpin...-0.21.1-r1.apk $ tar zxvf gnuchess-6.2.9-r1.apk $ tar zxvf libintl-0.21.1-r1.apk $ mv usr/bin/gnuchess scripts/ $ mv usr/lib/libintl.so.8.3.0 libs/libintl.so.8 NOW CONNECT YOUR KOBO TO YOUR PC: Copy your gnuchess binary from the scripts/ folder on the PC to the /mnt/onboard/.adds/koreader/scripts/ folder on the kobo. Copy new lib from the libs/ folder on the PC to the /mnt/onboard/.adds/koreader/libs/ folder on the kobo: libintl.so.8 Copy the usr/share/gnuchess folder on the PC to the /usr/share/ folder on the kobo: PLAY CHESS FROM fbpadkb TERMINAL: # . /korenv.sh # gnuchess -e GNU Chess 6.2.9 Copyright (C) 2021 Free Software Foundation, Inc.
