I have a similar problem. I can often cause a crash of my NVidia X server when ending an ediff session with emacs (emacs22-gtk, version emacs-22.2-ubuntu2).
To recreate: Open emacs, open two files in separate buffers, type M-x ediff-buffers, browse changes, then type 'q' to quit the ediff session. I'm running nvidia-glx-180 (version 180.44-0ubuntu1). ** Attachment added: "Xorg.0.log.old" http://launchpadlibrarian.net/27201352/Xorg.0.log.old -- xserver crash on closing a window https://bugs.launchpad.net/bugs/376099 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
