Can't believe this is on invalid! I got an MSI EX600 machine, which I have been using Ubuntu on since 9.10 without major hick-ups.
I have _switched_ from Ubuntu to Fedora now, since this bug really makes the system unworkable. There is nothing written in logs when this happens, although I know a way to fully reproduce the crash. Open your webbrowser and point to a resource-intensive website, like www.eurogamer.net. Click on one of the reviews or digital foundry face- offs. Now just scroll up and down. You'll notice that from time to time the browser screen refresh seems to hang just an instant. Continue to scroll up and down. You would be very lucky if the momentary hang doesn't result in a full lock-up after a few occurances. This bug is 100% reproducable. Since you can not work on the system for more than half an hour, Ubuntu becomes plain unusable, which is a shame. This happens on a fully clean install. With or without updating Nvidia drivers. Don't dismiss this. The bug is here, reproducable, blocking. https://www.google.com/#q=ubuntu+12.04+freezes+-installer Invalid -> Confirmed ** Changed in: ubuntu Status: Invalid => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996989 Title: Ubuntu 12.04 Freezes Frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/996989/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
