I disabled all acceleration in X, but that did not help, it crashed the same way as before: Option DRI false Option shadow true Option NoAccel True -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990914 Title: segmentation fault when running xkbcomp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/990914/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 990914] Re: segmentation fault when running xkbcomp
From http://www.x.org/wiki/Development/Documentation/ServerDebugging: Likewise, some gdb versions crash when starting the X server when attempting to run xkbcomp. This is, amazingly enough, a bug in the kernel's DRM code for suppressing some signals; it should be fixed in 2.6.28 if not earlier. You can disable XKB by passing the -kb option on the server's command line; obviously if you're trying to debug XKB this may cause you some problems and you're probably better off attaching gdb to a running X instead. Alternatively, disable DRI, but again, if DRI is the thing you're trying to debug, that won't help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990914 Title: segmentation fault when running xkbcomp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/990914/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

You are right, I started X using startx (without lightdm) and it crashed as well: Backtrace: 0: /usr/bin/X (xorg_backtrace+0x37) [0xf05f87] 1: /usr/bin/X (0xd7e000+0x18bd0a) [0xf09d0a] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0xaa640c] 3: /usr/bin/X (XkbComputeControlsNotify+0x123) [0xeb7bf3] 4: /usr/bin/X (0xd7e000+0x12e162) [0xeac162] 5: /usr/bin/X (0xd7e000+0x130e8a) [0xeaee8a] 6: /usr/bin/X (0xd7e000+0x37845) [0xdb5845] 7: /usr/bin/X (0xd7e000+0x2529a) [0xda329a] 8: /lib/i386-linux-gnu/libc.so.6 (__libc_start_main+0xf3) [0x4604d3] 9: /usr/bin/X (0xd7e000+0x255d9) [0xda35d9] Segmentation fault at address 0x6bb Caught signal 11 (Segmentation fault).

Thank you for your bug report, that's a segfault in X itself, not a lightdm bug ** Package changed: lightdm (Ubuntu) = xorg-server (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990914 Title: segmentation fault when running xkbcomp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/990914/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
