Instead of ltrace, can you get a backtrace with gdb? (gdb) bt

*** Bug 318861 has been marked as a duplicate of this bug. *** Wow, neat. I think I see the upstream commit that introduced the bug. I'm doing a scratch build that I think will fix it: http://koji.fedoraproject.org/koji/taskinfo?taskID=184406 Please test once that finishes. xorg-x11-server-Xorg-1.3.0.0-28.fc8.jx works for me. Rockin. Building as -29. |
Description of problem: With today's rawhide updates: Oct 04 09:10:32 Updated: xorg-x11-xtrans-devel - 1.0.3-5.fc8.i386 Oct 04 09:11:42 Updated: xorg-x11-server-Xorg - 1.3.0.0-27.fc8.i386 Oct 04 09:24:07 Updated: xorg-x11-xfs - 1:1.0.5-1.fc8.i386 Oct 04 09:24:55 Updated: xorg-x11-drv-ati - 6.7.194-2.fc8.i386 X hangs in an infinite loop starting up. ltrace showed an infinite sequence of: strcmp("1600x1200","1600x1200") = 0 .... Commenting out the Modes line (as shown below) allows X to start.
