I got the same problem, I upgrade from 13.04 to 13.10. This bug issue. Using Lenovo X230. And very annoying. The system hang. Nothing response. And one thing is very strange, If I'm using a USB mouse. When I unplug the USB mouse, and Plug it again. It seems no power supply to the mouse(very strange, Lenove DOSE change a main board for me, But the same thing happen, so I think this is not cause by the main board).
If some one freezing the keyboard and mouse, try to unplug your mouse, and plug again, try to see if the red light under mouse can see. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
