It happened to me as well. I semi-maximize a LibreOffice program to the left or right (holding the title bar to the left or right), then I maximize the window holding the title bar towards the top of the screen. The animation of fullscreen comes up, but the system freezes. The mouse works, but no clicks do. Also, the cursor stays with the "hand grabbing" icon.
This happened on a recently installed Ubuntu 13.10. -- 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
