Arch Linux on Paperwhite2

[HisDudeness]

Hey guys,

I just managed to get Archlinux running in chroot on my paperwhite 2.
Now I am trying to set up xorg but for lack of experience i have no idea how to proceed

I can run xapps like xeyes, xclock... but they use the already running kindle xserver.
When trying to start a xserver in chroot, I always get '(EE) no screens found(EE)'

I installed the fbdev driver, but i actually have no idea how to set the xorg.conf XD
Does anyone know how I could get the screen and multitouch running?
Or is there a way to start a 2nd xserver 'as an app' on top of the other one?

cheers

The error is correct, you only have a single display (hardware) set.

If you can't just use the running x-server, you will have to stop the one which is using your display hardware first.

Could you post a *.tar.gz of your Arch chroot directory somewhere for others to work with?
Plus any of the start/enter/exit/stop scripting you are using.

[HisDudeness]

sure!
here we go:

# To get ArchARM running on your Paperwhite2, do the following:

# SSH into your Kindle, then:

mkdir /mnt/us/archlinux             # create a directory of your choice
cd /mnt/us/archlinux
mkdir os 			
dd if=/dev/zero of=arch.img seek=750000000 bs=1 count=1 	# create image container
mke2fs -F -t ext3 arch.img	        # create ext3 filesystem of image
mknod /dev/loop7 b 7 7		# create loop device
losetup /dev/loop7 arch.img	# set loop device to image
mount -t ext3 /dev/loop7 os/	# mount it
			

# download the latest ArchARM v7 into your os directory
# either with wget:
wget http://os.archlinuxarm.org/os/ArchLinuxARM-armv7-latest.tar.gz

# or over ssh with scp:
scp ~/Downloads/ArchLinuxARM-armv7-latest.tar.gz root@192.168.2.2:/mnt/us/archlinux/os/ArchLinuxARM-armv7-latest.tar.gz

# extract the tar and then remove it
tar xzf ArchLinuxARM-armv7-latest.tar.gz
rm ArchLinuxARM-armv7-latest.tar.gz

#mount some directories for arch:
mount -o bind /dev/ /mnt/us/archlinux/os/dev
mount -t proc proc proc/
mount --rbind /sys sys/
mount --rbind /dev dev/

# copy the DNS settings
cp /etc/resolv.conf etc/resolv.conf

# and chroot into arch:
chroot /mnt/us/archlinux/os /bin/bash

#now try to run 
pacman -Syu

#and if it starts updating, everything is fine =)

you could now get some xapps like xclock or xeyes and display it:

xclock -geometry 300x300+150+250 -name "L:D_N:application_ID:xclock"

Thats where I am atm.

@knc1:
Thats what I thought...
The problem here is, everytime i stopped the xserver it immediately restarted, leaving me no chance to start mine. :/ I haven't figured out yet the service responsible for that...

[knc1]

You will have to dig through the upstart rules to find out what is keeping it running.

Some of the video examples (at least) have had to stop the x-server -
probably in posts by Geekmaster and/or twobob.

I have never needed to do it myself, so I don't have any links handy for you to check out.

stop lab126_gui is your new best friend.

stop lab126_gui is your new best friend.

-> indeed

It works fine now to run programs from arch and display it with the kindle xserver =)
I played around with vnc and other stuff but the limited diskspace is annoying.

I might dig out my raspberry and look into x11 forwarding instead...

[Ecaz]

Hey can you post a few pictures of your Kindle running X?

I'd like to see that :-)

[NiLuJe]

@Ecaz: Look at your own? .

(Every Kindle running FW 5.x already runs X ).

[HisDudeness]

i just found out what triggers the xserver to automatically restart:

If you have a look into /etc/upstart/x_monitor.conf
you can see that the first line is responsible to start the lxinit in case of a crash. So if you are annoyed by frequent xorg resets -> uncomment it

I also played around with the X11 forwarding this morning. Parallel to the xforwarding on the kindle I run a synergy client on the arch chroot and the server on my laptop. (Synergy sends mouse and keyboard to a remote host).
This way I can use the touch of the pw as well as my mouse and keyboard =)

@Ecaz:
here a pic of the Kindle updating Steam

I tried following your guide from a terminal emulator. It was going well until I tried to untar the Archlinux tar.gz and i got a slew of errors stating

"cannot create symlink from...
Operation not permitted"

Any ideas how to fix this?

The USB storage area is a FAT32 filesystem.
B.G., in his wisdom, did not (and does not) support symbolic links.

Somewhere (early on) in that guide should be the directions for creating a ext2 (or ext3) filesystem in a file and then mounting that file as the destination for your arch distribution.

I see. I did catch that but my SSH must have missed that step and was trying to untar it into the Fat32. Thanks for the direction.

and be careful to have enough free diskspace before extracting...
- saves you a lot of annoying crashes & rebooting

this is really nice, and thanks for the guide, it is very helpful!
the pw2 has more power than the pw1 right, would it run a lot worse?
i assume the guide would be the same...

the touch screen just 'works'?
i'll see how hard it will be to get synergy running with my mac.

-edit. not just more powerful, it has a whole different cpu, i don't think pw1 is arm right?
anyway thanks

Wrong.
All except the K1 are Freescale ARM, the K1 is TexasInstruments ARM.

The PW1 uses one of the Freescale iMX6 SoC chips.
