I agree, it's looking more and more like a kernel bug. I have added the package linux to this bug report. For kernel bugs there is a whole new list of required information (see https://wiki.ubuntu.com/KernelTeamBugPolicies). At least you will need to upload the output of `uname -a`, `cat /proc/version/signature`, and `dmesg`. These should be uploaded as separate files. If you want, you can do it by sending the files as attachements to <bugnr>@bugs.launchpad.net, as this will only generate one comment (the web interface is limited in this respect, see bug 82652).
About your last test, when you pinged the computer and it stopped replying after you put the VGA cable in, was your computer on wireless or wired ethernet? I think it may be easier to bring down the wireless, since it is only started after you log in, but I'm not sure. Also I'm impressed that you could ping your computer without having another computer available - how did you do that? ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete => Confirmed -- [iGM45] Connecting external monitor causes system to lock up. https://bugs.launchpad.net/bugs/319717 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
