Description Miklos Vajna 2009-06-08 19:49:09 UTC
Hi,

I upgraded to "X.Org X Server 1.6.1" recently and first I noticed that the updated xf86-video-intel 2.7.1 had a totally screwed up output. I could not make a screenshot of it, basically there were some output (ie it was not a black screen), but it was unreadable. Then I updated xf86-video-intel to latest git (commit 66ceedc) and I got an other type of corruption: the picture is almost OK, but the some fonts are unreadable:

The weird thing is that after this, I downgraded xf86-video-intel back to 2.7.1 and everything was fine:

... till I rebooted. So I can reproduce this: after reboot 2.7.1 is broken, upgrading to git is not working either, but after this when I downgrade everything is fine again.

Anytime I put Option "NoAccel" "false" to xorg.conf, both drivers are okay.

System info:

lspci output:

00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)

kernel: 2.6.29.3, i686

distro: Frugalware Linux 1.1pre1

The notebook is a Clevo M450C.

xorg.conf: http://frugalware.org/~vmiklos/logs/xf86-video-intel/xorg.conf

Xorg.0.log for both driver versions:

Let me know if I missed any required info. :)

Thanks!

Does this still exist in xf86-video-intel master branch tip?

The problem went away after upgrading kernel from 2.6.29 to 2.6.30.

Thanks!
