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-X, which is subscribed to xorg-server in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
