Fernando, good work! That shows a nearly perfect backtrace, but we're missing symbols for the first two calls (which is probably where the crash is):
#0 0x0057ffb4 in pixman_region_equal () from /usr/lib/libpixman-1.so.0 No symbol table info available. #1 0x0018e798 in ?? () from /usr/lib/xorg/modules/drivers/openchrome_drv.so No symbol table info available. Can you install the dbgsym packages for pixman and the openchrome driver and do it once more? Also, I should also mention your backtrace is completely different than what's shown in other people's Xorg.0.log.old so is probably some other unrelated X crash. (Like I mention, every type of X crash results in the same thing - dropping you back to the login screen). Your syslog also shows that the kernel is very sick (but not in the graphics drm stack). Hard to tell if those errors relate to the crash you're seeing, but if I had to guess, it looks like something deeper is wrong in your system and X crashing is just a side effect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/778490 Title: Random logout after upgrading to Natty Narwhal 11.04 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
