Well, today the problem appeared again. Now I have commented out all the custom xorg.conf options, let's see what happens.
This is the backtrace of today's crash: Backtrace: 0: /usr/bin/X(xf86SigHandler+0x6a) [0x48402a] 1: /lib/libc.so.6 [0x7f704b1b8100] 2: /usr/lib/xorg/modules/drivers//nvidia_drv.so(_nv000759X+0x68) [0x7f7048c54b78] -- gdm_slave_xioerror_handler: Fatal X error https://bugs.launchpad.net/bugs/152648 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
