Something similar happened to me in Ubuntu 12.10. I accidentally pressed Super, getting the dashboard, then pressed it again to close it. After this, keyboard and mouse stopped working. All of the apps continued to run just fine - but I couldn't interact with them.
Xorg.log had this line at the end: [ 17877.120] [mi] Increasing EQ size to 512 to prevent dropped events. When I killed compiz, everything started working again. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/755099 Title: X lockup caused by compiz/unity To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/755099/+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
