Created attachment 318150 [details] xorg log that should contain info from the time of the crash Description of problem: From time to time (really scarce, just a couple of occurrences in a month) xorg goes mad - screen changes to some sort of multicolour pattern, if I recall correctly mouse is still there, keyboard input is blocked. After a while x crashes and tries to restart but ends up in the same state. This repeats several time after X freezes altogether. It seems the computer is not dead, since kernel is still receiving signal from the power button and is able to shut down the system correctly. Last time it happened I was switching tabs in firefox. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.5.0-2.fc9.i386 How reproducible: Random, scarce. Steps to Reproduce: Not sure, don't know about a pattern that is sure way to cause this. Actual results: Graphic output is broken, keyboard input is blocked, x crashes after a while Expected results: x is continuing to stay alive and working Additional info: Might be a problem with AIGLX and compositing via metacity turned on, I don't remember this happening when I used to have compositing off (but due to the seemingly random nature, I just might have missed it).

I've just been "lucky" to experience the issue again in a relatively short time. I didn't mentioned that in the original report that it happened when I tried closing tab in firefox, this time it happened when I tried closing tab in epiphany so it might be related (both browsers use gecko). I'll attach new xorg log, though I think it will be pretty much the same. I've also taken a photo of the screen with my mobile phone (at that time X already stopped reloading and were just frozen). I'll attach it.

Created attachment 319476 [details] photo of the frozen X Sorry about the bad quality - it was taken by a mobile phone - but you'll get what it looks like from it easily. You can also notice the cursor in there (which just a few moments before I took the photo froze as well).
Created attachment 326582 [details] another xorg.log in my case the crash seems to happen consistently with a mythfrontend error where the front end sound continues but X crashes behind it Dec 10 18:26:26 tveye2 kernel: mythfrontend[14146] general protection ip:2dd3221 sp:ac2fe190 error:0 in libqt-mt.so.3.3.8[2837000+837000] Dec 10 19:47:32 tveye2 kernel: mythfrontend[4164] general protection ip:2dd3221 sp:ace74190 error:0 in libqt-mt.so.3.3.8[2837000+837000]
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. 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 '9'. 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 9'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 9 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
