intel video driver produces visual corruption on 945GM chipset

[Paul Holcomb]

Binary package hint: xserver-xorg-video-intel

This is a possible dupe of bug 150597
but its a different chipset, so its supposed to be reported as a different bug

$lspci |grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller

$ aptitude show xserver-xorg-video-intel
Package: xserver-xorg-video-intel
Version: 2:2.1.1-0ubuntu9

$ uname -a
Linux legba 2.6.22-14-generic #1 SMP Sun Oct 14 21:45:15 GMT 2007 x86_64 GNU/Linux

both the vertical and horizontal corruption

I would like to know if xserver-xorg is partially guilty on this history ! It is suffering a lot.
There are issues with gdm, npviewer, cups, hfs and mainly Compiz.real.

Could you please check this against Hardy Alpha-4 to see if it is still occuring? We're using EXA and a newer intel driver on Hardy, which may resolve it.

If it does not, can you also try activating the "greedy" migration option (this solved several issues on 965GM hardware and might be needed for 945 too). For example:

Section "Device"
  ....
        Driver "intel"
        Option "AccelMethod" "EXA"
        Option "MigrationHeuristic" "greedy"
  ....
EndSection

Let us know either way, thanks in advance!

Xorg before applying changes above in xorg.conf

[mabovo (mabovo)]

Xorg after activating "greedy" in xorg.conf

Section "Device"
 Identifier "Configured Video Device"
        Driver "intel"
        Option "AccelMethod" "EXA"
        Option "MigrationHeuristic" "greedy"
EndSection

Also another information that You don't like at much :)
mabovo@macbook:~$ glxgears
7849 frames in 5.0 seconds = 1569.723 FPS
8065 frames in 5.0 seconds = 1612.917 FPS

7983 frames in 5.0 seconds = 1596.512 FPS

Is this the latest intel driver being tested in Hardy you mentioned above ?

It will be -intel 2ubuntu6 when it is finished uploading probably some time within the day.

[Bryce Harrington (bryce)]

Hi mavobo, have you had a chance to test it?

[mabovo (mabovo)]

Hi Bryce, testing now with 2.2.1-1ubuntu3 working out of the box. No problems with Compiz or Firefox3. Video response is very fast and no corruption at all (i945GM).
Glxgears improved more and more :)

[mabovo (mabovo)]

New xserver-xorg-video-intel driver 2.2.1-1ubuntu4 crash with openarena

[mabovo (mabovo)]

Openarena is not crashing with 2.6.24-12.22 and xserver-xorg-video-itel 2.2.1-1ubuntu5

[Bryce Harrington (bryce)]

mabovo, thanks for reporting the issues are fixed.

Paul, please reopen if the issue still persists.
