Hello Alan. Actually, if I am not mistaken, the key combo itself is for restarting X, not killing it. That would also explain why it works on all of my machines. I would assume there is some flaw in your xorg.conf or (which is more likely) the graphics driver, preventing X from restarting properly. I am moving this bug to the xorg package for further investigation.
Thank you for this report, and have a nice day :) ** Changed in: xorg (Ubuntu) Sourcepackagename: kdebase-workspace => xorg -- kde4 KDM does not restart X when killed with ctrl+alt+backspace https://bugs.launchpad.net/bugs/315819 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
