I'm also experiencing this type of problem. It only started happening to me in the last couple of months though (when I upgraded from my old nvidia 7600 GT to the nvidia 9400GT card). I used to use a different nvidia driver (173 maybe???) but now that wouldn't work and I had to use the 180 version. Since then I had sparatically noticed silly things most of which were not reproducable but the computer would suddenly power off both monitors and then stay frozen or sometimes reboot itself.
I finally found a game that I could start up which would reproduce the error 100% of the time called Heroes of Newerth (in beta so requires permission to download the game). The game would startup just fine and start downloading patches and stuff and then after almost exactly 15 seconds, in the middle of it downloading the entire computer would lock up and crash just like what I had randomly noticed in the past. Repeating the process implies that the download wasn't the problem because it resumes where it left off and finishes up more of the upgrade process but it keeps crashing after about 15 seconds (after the login process, doesn't crash at the login screen ever). I had sometimes noticed that Google Chrome would do the same thing if you started typing in the address bar. It would suddenly go extremely slow on its lookups and then power off the computer. These things only happen on my computers using the 180 (or 185 in karmic cases) computers. The intel and ati computers have no problems what so ever with anything. And I don't recall my older video card ever having problems (but it used the version before 180). -- 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
