I seem to have the same or a closely related problem, my mouse behaves in exactly the same way as described above!
After a fresh install of 13.04, I installed gnome-shell, which is when the problem started. However, It's still there after I have uninstalled gnome-shell. It is always present after the first login after booting. Logging out and back in removes the issue. Any ideas what the issue might be? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1181666 Title: gnome-shell randomly blocks mouse from working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1181666/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
