Hi Salva, A couple things. First, for backtraces, gotta get a complete backtrace - see http://wiki.ubuntu.com/X/Backtracing for guidance.
Second, I see you have virtualbox installed. That puts some different drivers on your system which can cause conflicts. Please uninstall that (and purge it if necessary), and see if you can reproduce the crash then. If you can, then get a full backtrace as above. ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Confirmed => Incomplete -- vinagre and x11vnc -ncache 10 crash X https://bugs.launchpad.net/bugs/545019 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
