For me this is still an issue (on the stable 13.10), but (un)fortunately I have no idea how to reproduce it or what factors (do not) contribute to it.
So far, I seem to have found: - the version of nvidia-drivers or the use of nouveau is irrelevant - in Gnome, I have the impression that a freeze is much more likely when using multiple workspaces - it seems to happen very much less frequently when using Unity than with Gnome sessions (but I probably don't use the workspaces in Unity as much as in Gnome) Currently, I experience a freeze in Gnome-Shell within 1-3 hours after startup/reboot. I will happily grab the daily snapshot and see if it still happens there and then upload the apport-collect data. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1184451 Title: Ubuntu 13.10 random screen freeze while Normal OS activites To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1184451/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
