Release: Ubuntu 13.04
Version: 2:2.21.6-0ubuntu4
Obtained result: X fails to start with the provided xserver-xorg-video-intel package when using custom built fglrx packages, which is a regression from previous versions.
Expected result: X starts correctly with available 3D acceleration.
Description:
I have a Radeon HD 7670M muxless hybrid graphic card. After upgrading to Raring, X fell back to low-graphics mode (which was half-expected) and the fglrx versions offered in the official Ubuntu repositories didn't work either (resulting in a X segfault).
After some testing, I created a package of the latest fglrx drivers as per https://help.ubuntu.com/community/BinaryDriverHowto/ATI , resulting in version 2:12.104. This also resulted on a X failure, although not with a segfault, but with the following error (log attached):
[ 55.455] (EE) fglrx(0): Failed to allocate caches, disabling RENDER acceleration
[ 55.459] (EE) fglrx(0): [intel] Failed to allocate video resources for front buffer 1366x768 at depth 24
Downgrading the xserver-xorg-video-intel package to the Quantal 2:2.20.2-1ubuntu1 version fixes the problem. I have not tried to pinpoint the exact version where the regression occurs; I chose 2.20.2 because it was suggested elsewhere and because 2.20.3 is known to be problematic with fglrx (as per #1068404 ).
This has also been reported in Gentoo:
http://forums.gentoo.org/viewtopic-t-949372-start-0.html
Even though the bug involves fglrx related, I am reporting it because it's xserver-xorg-video-intel which seems to blame and I can confirm that earlier versions of the package fix the issue. This same video card also worked well in Quantal, although it did need the packages from andrikos' PPA to behave.
From an usability standpoint, it's also important to note that, as I mentioned before, the Ubuntu-provided fglrx (both regular and -updates) plus the 2:2.21.6-0ubuntu4 version of the intel server resulted in a X segfault for me. The fglrx versions in Andrikos' PPA also segfaulted. I think that bug is unrelated to this one. However, I can check whether the Ubuntu-provided fglrx packages work with this server version, and try to reproduce the other bug and report it separately if you wish (I was dumb enough not to save the log). |
