I'm having the exact same problem. It tends to happen when I don't touch the computer for a while (aka watching a video fullscreen or I'm away and the screensaver has turned on). However, it doesn't always happen (two nights ago my computer didn't freeze while I slept but last night it did).
I can't find any errors in the logs either. -- Frequent total system freezes after upgrade to Hardy https://bugs.launchpad.net/bugs/214108 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
