Same thing happens to me also after upgrading to 10.10 from 10.04. Dell D820 with nvidia and external monitor + xinerama.
Here is some some observations: - Disabling xinerama get rid of the crash. - Interesting thing is that I installed "qgit" instead and it crashes the whole X also. - I don't think git itself can crash X - probably not a bug in tcl/tk or qt - looks like a bug in xorg which crashes on certain drawing primitive used by both gitk and qgit. -- gitk crashes entire X session https://bugs.launchpad.net/bugs/659473 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
