Hi All
I am a linux user and have been trying to get my phone to run linux too... so finally after a lot of messing around i got Ubuntu 10.04 aka Lucid runing on my phone.

I used a stack image provided by https://code.google.com/p/android-cruft/ This image is a stripped down version of the Ubuntu img file and hence a good setup for customization.

However the problems i had with this as well as other images so far was following.

1) 2GB is very small when you want and LXDE to run : good for showoff not good for actual working conditions.
2) bootubuntu or bootdebian scripts won't let me keep the system mounted.. as soon as i exit the shell my ubuntu gets unmounted.
3) All the scripts wont play well with APP2SD or simmilar applications.

REQUIRED:

1. Rooted and busybox installed phone.
2. Android terminal software would be needed for commands.
3. Android VNC Viewer.

GUIDE FOLLOWS BELOW

************* USER PORTION START HERE ******************

******STEPS TO FOLLOW ****************

1) extract the content and copy then to /sdcard/ubuntu
2) run 'sh ubuntu.sh' only once.
3) run 'starttux' (is now made to work without userinput so if needed you can place it is startup using gscripts.)
4) run 'tuxcmd'

a) 'ui' inside tuxcmd to start vnc server
to use GUI use any vncviwer and connect to localhost:5901
NOTE : VNCPASSWORD : 12345678
b) to kill vnc server : use 'killui'
5) when you want to stop ubuntu 'stoptux'

********** STEPS END HERE ************

********** THINGS TO KNOW ************

The whole script portion visible is divided into 4 scripts.

1. Ubuntu.sh <- setup script required to be run once in whole lifecycle.
2. starttux <- chroot setup script required to be run after every reboot.
3. tuxcmd <- script to get console based access to ubuntu
4. stoptux <- script to stop linux.

Besides these 4 files two important commands are available when you login to tuxcmd.

1. `ui` <- used to start the vnc server
2. `killui` <- used to stop the vnc server

once you have the image inside tuxcmd you can run vncpasswd to change password.
to use GUI use any vncviwer available in android market.
point it to localhost:5901.
NOTE : VNC PASSWORD : 12345678

KILLUI

kill -KILL `pidof Xtightvnc` 
rm /tmp/.X11-unix/X1

These launcher Settings are obtained using VNC xstartup file
so posting some sample xstartup files

for default GNOME UI

#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
"$VNCDESKTOP Desktop" &
export XKL_XMODMAP_DISABLE=1
/etc/X11/Xsession

for LXDE same startup file becomes

#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
icewm &
lxsession

for netbook i am using this xstartup

#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
"$VNCDESKTOP Desktop" &
x-window-manager &
export XKL_XMODMAP_DISABLE=1
maximus &
netbook-launcher-efl &

Running Smothly.

However i prefer using console more then gui so for me CLI is smooth.

Thats all what we need
Great work mate....

pretty cool, well done mate
however, the X10's screen is 854x480, not 850x480 (in the UI script)

Thanks

I did tried 854x480 however the VNC Server every time was showing me resolution as 856x480 and 2 pixels where floating off the screen

that's why i prefered 850 and fixed value.
