[i855] display corruption after update

kernel 2.6.27-9-generic booting error.jpg

Sorry, I forgot to ask - I assume kernel 2.6.27-9 is the latest one which is currently receiving updates.

If I keep on using the kernel 2.6.27-7 then how I am going to get the updates?

What shall I do to fix the kernel 2.6.27-9 is I can't even boot the computer from it?

Hope to hearing from the Ubuntu team.

Thanks and regards

There is a newer 2.6.27-11 kernel, please test and let us know your results. Thanks.

Dear Leann,

After I reinstalled Linux (see my first post above) I was not downloading any automatic updates for a few days. Used kernel 2.6.27-7 and everything was OK. Did not try to boot from kernel 2.6.27-9 anymore as it was causing problems.

Today (07/02/2009) I downloaded 244 automatic updates (forgot I should not do it :)) and after restart indeed notices that I have one extra kernel - 2.6.27-11. It was causing the same problem, so the computer is unusable.

But the worst part is that the kernel 2.6.27-7 which was working perfectly after re-installation of Linux is now also screwed up! The same problem.

So I guess now empirically I can confirm that starting from kernel 2.6.27-9 there was some update to a video card of whatever it might be, which causes my monitor to corrupt. Maybe they forgot to include the driver for my monitor (as it is a pretty old Acer tablet PC of 10.4 inch), which is not standard.

I would appreciate your response. I hope the bug can be fixed, otherwise I will either sit without any updates at all or re-install Linux every time I run updates by mistake.

Thanks and regards.

You mention you still experience issues even if you boot back into the previously working 2.6.27-7 kernel, this would seem to then indicate that it was one of the other 244 updates you pulled in that is likely causing this regression and not the kernel. Seems related to xorg. Please attach your /var/log/Xorg.0.log .

Dear Leann,

Please see attached the log file.

Thanks a hope to hear from you soon.

I have had the same problem. After a few clean installs I worked out the problem. It isn't the kernel but the display driver. When you first install ubuntu you need lock the version of the xserver display driver. If you install the updates a new driver version will be installed which makes the screen go haywire.

Instructions (DO THIS BEFORE INSTALLING ANY UPDATES):
1. Go into Synaptic Package Manager
2. Search for: xserver-xorg-video-intel
3. Click Package --> Lock Version

You can now install any other updates.

Reassigning to xserver-xorg-video-intel.

You said you had to lock the version of the xserver display driver. What version do you have to lock it to? I.e., which specific version carries the regression?

The version I have locked it at is: 2:2.4.1-1ubuntu10

moving to bug #350032 as is the same one
