I had this bug sporadically, too. I cannot reproduce it, though. Usually pressed Ctrl-Alt-F1, logged in on console and killed X. Now I have tried to do the
sudo modprobe -r psmouse && sudo modprobe psmouse This worked! I am using two mice with Kubuntu 12.04, namely the builtin AlpsPS/2 ALPS DualPoint TouchPad and Logitech Bluetooth Mouse M555b. The problem appeared in different applications, e.g. firefox or when unlocking the screensaver on KDE. -- 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/41301 Title: Mouse clicks stop working sporadically To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/41301/+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
