Done.

CHANGELOG v0.2.0 ~ 0.3.0

add xfce4

[schuhumi]

Hi zaoqi,

that's a nice tool! And I certainly recognize some things I found a small problem, in line seven of the script to start XFCE https://github.com/zaoqi/kual-linuxd...ce4.user.sh#L7

In this command to find the window size:

SIZE=$(xwininfo -root -display :0 | egrep "geometry" | cut -d " "  -f4)

I run this from within the chroot, as the Kindle OS doesn't have egrep (at least mine, "chroot.xfce4.user.sh: line 7: egrep: not found"). Xephyr then gets confused with its arguments and chokes on the color depth:

Fatal server error:
(EE) Unrecognized option: 4

Also I found out that the loop devices don't get disassociated automatically when umounting, you can check like this:

[root@kindle kual-linuxdeploy-armhf]# cat /sys/block/loop*/loop/backing_file 
/dev/mmcblk0p4
/mnt/us/extensions/kual-linuxdeploy-armhf/rootfs.img (deleted)
/mnt/us/extensions/kual-linuxdeploy-armhf/rootfs.img
/usr/share/X11/xkb.sqsh
/usr/java/lib/fonts.sqsh
/etc/kdb.src.sqsh
/usr/lib/locale.sqsh
/usr/share/keyboard.sqsh
/opt/var/local.sqsh
/mnt/us/extensions/kual-linuxdeploy-armhf/rootfs.img (deleted)
/mnt/us/extensions/kual-linuxdeploy-armhf/rootfs.img (deleted)

That for me leads to a) running out of loop devices at one point (max 16) b) storage doesn't get freed when deleting the umounted image (df -h). Thus I disassociate it manually:

LOOPDEV="$(mount | grep loop | grep /tmp/alpine | cut -d" " -f1)"
... umounts ...
losetup -d $LOOPDEV

And a small thing: In my dotfiles I archive dconf dumps now as well. These have to be read in upon initialization as well though, e.g. like this

dconf load /org/onboard/ < ~/.config/org_onboard.dconf.dump

Just because I saw you install onboard too.. I switchted to Mate now, but currently the XFCE config is also still in the repo, so you can update the version you clone if you want.

Nice work! And your scripts look way more elegant than mine

A stupid question:Could it afford normally use Chrome?Or because of the poor performance it is just a funny dream?

Someone successfully ran Chrome on the Kindle. This tool may work, but I have not tested it.

Works nicely except for xfce. My KT hangs at random points through the xfce install, perhaps due to lower system RAM - my KT has 256MB RAM whereas your KT3 has 512MB, I think. However, even installing a 1GB swap file does not seem to help, so for now I am left with linux only running in text mode.

Any ideas?

[mrHedgehog]

Does this install as dualboot or does it overwrite Kindle OS? Thanks!

[NiLuJe]

Read the title, there's two very big hints in it.

1. KUAL.

2. Can't have a chroot without a host.

[mrHedgehog]

Alright. Thanks.
