I'm experiencing similar, however I don't have the screen locked (i.e. I don't need to type in my password after the screensaver has activated). I'm also running Gnome-Shell.
After ten mins or so, my screen blanks (as I don't have any screensaver set). When I move the mouse or touch a key to activate the screen, everything comes back as it should, however soon after an error comes up saying there is a problem with the screensaver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/849600 Title: gnome-screensaver crashed with SIGSEGV in g_main_context_dispatch() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/849600/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
