Same problem here and on 3 other laptops in my lab (2x thinkpad and 1x macbook air).
My Macbook Pro 11.3 has Kernel 3.13. When the screen freezes, sound (e.g., skype) still works and I can move the mouse but not click. I 'solve' this by going to the terminal and restarting lightdm: 'sudo service lightdm restart' but of course this is still not a real solution. -- 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
