Red Hat Bugzilla – Bug 473163
Xorg crashes with openchrome driver on VIA Unichrome chip when using some acceleration methods
Last modified: 2009-12-18 01:57:42 EST
Description of problem:
After using some graphic-card accelerated programs, like or projectM, X will starts acting weird and only updating certain parts of the screen (like when moving windows, only the inside of the window is updated). Restarting X will crash the system altogether. Using full-screen application with 3D acceleration also crash xorg.
Version-Release number of selected component (if applicable):
I've noticed glitches/crashes with the following applications: glchess, openarena and projectM.
Steps to Reproduce:
1. Start X with openchrome drive on Unichrome chip.
2. Start projectM.
3. projectM will cease to render, rendering becomes unreliable, and restarting X will crash the system.
Crashes, glitches in X.
Smooth accelerated graphics.
this is involving 3D, not 2D so the bug is in the unichrome DRI driver, which is unfortunately in a poor state at the moment. This is likely to change in a not too distant future. Re-assigning to Mesa.
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below.
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '10'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
