    Talking [SOLVED] IBM ThinkPad 1161 (i Series 1200) screen resolution on Xubuntu 8.04

    Using advice from this site I made a working xorg.conf supporting the resolution 1024x768 in full screen.

    To use this xorg.conf in your system open as root the file /etc/X11/xorg.conf with the following command:

    sudo mousepad /etc/X11/xorg.conf
    replace the file content with the code posted above and reboot your system.

    For more advice on X configuration do refer to the following pages:

    Talking Re: [resolved] IBM ThinkPad 1161 (i Series 1200) screen resolution on Xubuntu 8.04

    I just used this solution to fix the display on my VersaTab II (also called a WalkAbout Hammerhead XRT), running Ubuntu 9.04. I did have to make a couple modifications that I thought I would explain here.

    I had to change the Device Bus ID (obviously) - to get your Bus ID, run lspci, find your VGA compatible controller (Silicon Motion, Inc. SM712 LynxEM+ on my system), and your Bus ID is the series of numbers on the left.
    > lspci
    02:05.0 VGA compatible controller: Silicon Motion, Inc. SM712 LynxEM+ (rev a0)
    The format in the lspci printout is different from what is required in the xorg file... the last two numbers in the lspci display are separated by a period (.); in the xorg file, this should be a colon {:}, as shown above.

    The other thing I changed was my default resolution - in the example above it's 1024x768, but the max res on my machine is 800x600, so I changed it accordingly. Hope that helps others.

    Many thanks to virgo977virgo!!!
