Screen scrambled after sid update - cursor is working fine


This is a strange issue. I have hosed my Xorg so that the mouse cursor/keyboard is working but the screen is scrabbled.
see pic below:

http://i44.tinypic.com/25oug4z.jpg

The mouse cursor looks fine and I can tab around the screen and the scrabbled background changes as if it were a hardware issue. I do think this is a hard ware issue because my xubuntu partition is booting and displaying correctly. The Computer is a Thinkpad G41 type 2886 - 5TU

I have tried :
Code:
Using apt-get to remove  xserver* and xorg* , then installing everything
Using apt-get to remove  gdm and , then installing gdm
dpkg-reconfigure xserver-xorg
dpkg-reconfigure -phigh xserver-xorg
dpkg-reconfigure xorg
What should I do? Any advice or links would be greatly appreciated!

here is my lspci output from my working xubuntu partion

Maybe this:
https://bugs.freedesktop.org/show_bug.cgi?id=21246

Could be the kernel mode setting which tries to detect some timings but looks like it fails.
Or a bug in the driver

Can you try a kernel 2.6.28 for example? Or take the one from testing if that's easier.
I think KMS was introduced in 2.6.29

Hi,

Try looking on the sidux forums for a solution:

www.sidux.com


I had a similar problem and switched the driver I used to 'vesa' to get a quick solution and allow me to carry on working.


Not got round to finding a full solution as yet.

Also,

Macondo on the "post installation setup" sticky on the forum - last page - alludes to a similar problem/solution.


Regards.

I edited my grub list and booted with an older kernel and it worked! Thanks!

Do you know of any upgrade strategies that preview such horrifying error? (like "nevered install a XX.1 kernel" or "never ever upgrade")
