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

[virgo977virgo]

Using advice from this site http://d.hatena.ne.jp/kamekamekame877/20090122 I made a working xorg.conf supporting the resolution 1024x768 in full screen.

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!!!
