[i855] ghosting and rubbish on screen following upgrade

[paledread]

running ubuntu intrepid 8.10 on a motion computing m1400 tablet.

an upgrade of xserver-xorg-video-intel from version 2%3a2.4.1-1ubuntu10_i386 to 2:2.4.1-1_ubuntu10.3 was offered by the update-manager.

following the update, the gdm log-in screen was showing a secondary ghosting of the log-in screen together with some other garbage. some degree of operation was possible, and a log-in was achieved. the desktop after log-in showed the same video problems, with the left half of the screen ok, and the right half confused.

downgrading to the previous intel driver version fixed the problem.

Thank you for reporting this bug. It seems that you are not the only one experiencing problems with the ubuntu10.3 version of the driver. Could you help us debug this problem by upgrading to 10.3 again and attaching the following files:
- /var/log/Xorg.0.log
- the output of `lspci -vvnn`
- /etc/X11/xorg.conf if you made an changes there
(then you can downgrade again).
It may also be useful to have the Xorg.0.log from the downgraded version for comparison.

Geir,

Attached are good and bad Xorg.0.logs, and good and bad lspci -vvnn,
although I guess these would be the same.

My xorg.conf is also attached although I made no changes between the 2
intel driver changes.

Thanks for your efforts.

A single fact can spoil a good argument.

Thank you for the files, I'm setting the status to confirmed.

I can confirm this behavior on my Motion Computing LE1700 tablet PC. The updated intel driver from the updates repository consistently causes ghosting. I have reverted to the 10.3 original package and that fixed the problem.

[Russ Williams (h-launchpad-net-russcon-org)]

I confirm this problem also on a Motion LE1600 tablet computer after installing Ubuntu 8.10 (and the screen was find) and then installing all the many (128?) updates (and the screen was corrupted in exactly the way described, with right half really trashed).

Tried pinning the older version via /etc/apt/preferences without success (apt-get install complains that xserver is a virtual package and that there's no candidate package...), so then I used Synaptic to downgrade to previous version of xserver-xorg-video-intel and it seems to have solved it, though it's unclear if Ubuntu will continually want to upgrade it again or not. If anyone can describe a good/standard/correct way to downgrade this package and keep it from updating to the later version that breaks Motion PCs, please do.

I never would have figured out what was going on if not for finding this bug report, so many thanks to the original bug reporter paledread.
