Xorg.0.log.old; backtrace at end of log file.
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.

Xorg.0.log generated with no xorg.conf
X failed to start
I've attached my xorg.conf. The Xorg.0.log from an X session that died is in comment 1, id=144298. I've also attached the Xorg.0.log where I had no xorg.conf. As you can see, X failed to start. *** Bug 240002 has been marked as a duplicate of this bug. *** *** Bug 246313 has been marked as a duplicate of this bug. *** *** Bug 246797 has been marked as a duplicate of this bug. *** I can reproduce this 100% reliably on xorg-x11-server-Xorg-1.3.0.0-9.fc7.x86_64 (fresh install of Fedora 7 with updates); the catch is that it requires Matlab (tested with R2006b). The Matlab can be running on a remote machine with trusted X11 forwarding (provided it has OpenGL support) or on the local machine. Simply type: $ matlab -nodesktop > [x y z v] = flow; > isosurface(x,y,z,v,0); A new window appears containing a graph. Grab the titlebar of this new window, and as soon as you attempt to move it, *boom*. Not posting the traceback since it's pretty similar to the one here and the one in bug 246313.

Created attachment 159216 [details] Patch for Mesa fixing the null-context bug This bug seems to be the same as Debian Bug 430948 [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=430948] and SuSE bug 211314 [https://bugzilla.novell.com/show_bug.cgi?id=211314]. The Debian bug report points to an upstream bug and a patch that fixes the issue. I've applied the patch mentioned there (needed a couple of edits) to the Fedora 7 version of mesa-6.5.2 and regenerated it. The regenerated patch is attached. Recompiling the SRPM for xorg-x11-server after applying this patch to mesa has fixed the issue for me with Matlab as far as I can tell. *** Bug 243454 has been marked as a duplicate of this bug. *** Attachment 159984 [details] and attachment 159985 [details] of bug 243454 are upstream patches for this problem. The upstream patch I attached in comment 11 of this bug is actually a more complete solution than attachment 159984 [details] - the latter essentially just ignores the problem. I'm not sure, but I think attachment 159985 [details] fixes a different (but possibly related) bug. This bug is believed to be fixed as of xorg-x11-server 1.3.0.0-19.fc8, in tomorrow's rawhide. Please update, and move this bug back to ASSIGNED if the issue still occurs for you. Will there be an update for fc7? I currently have 1.3.0.0-9.fc7 and the problem still occurs. Agreed, getting this into F7 would be a good idea; not all of us can run rawhide or F8 beta builds regularly regularly. ;-) I just had a simular problem in FC6. Closed an active Firefox session with 3 tabs still open and X did its crash thing. FWIW the last few lines of Xorg.0.log.old follows; (II) <default pointer>: ps2EnableDataReporting: succeeded Warning: font renderer for ".pcf" already registered at priority 0 Warning: font renderer for ".pcf.Z" already registered at priority 0 Warning: font renderer for ".pcf.gz" already registered at priority 0 Warning: font renderer for ".snf" already registered at priority 0 Warning: font renderer for ".snf.Z" already registered at priority 0 Warning: font renderer for ".snf.gz" already registered at priority 0 Warning: font renderer for ".bdf" already registered at priority 0 Warning: font renderer for ".bdf.Z" already registered at priority 0 Warning: font renderer for ".bdf.gz" already registered at priority 0 Warning: font renderer for ".pmf" already registered at priority 0 FreeFontPath: FPE "unix/:7100" refcount is 2, should be 1; fixing. Based on the date this bug was created, it appears to have been reported against rawhide during the development of a Fedora release that is no longer maintained. In order to refocus our efforts as a project we are flagging all of the open bugs for releases which are no longer maintained. If this bug remains in NEEDINFO thirty (30) days from now, we will automatically close it. If you can reproduce this bug in a maintained Fedora version (7, 8, or rawhide), please change this bug to the respective version and change the status to ASSIGNED. (If you're unable to change the bug's version or status, add a comment to the bug and someone will change it for you.) Thanks for your help, and we apologize again that we haven't handled these issues to this point. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again. This bug has been in NEEDINFO for more than 30 days since feedback was first requested. As a result we are closing it. If you can reproduce this bug in the future against a maintained Fedora version please feel free to reopen it against that version. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp |
