I have this sort of problem with 11.04 as well with Mint12 (KDE) after installing anew. Suggestion "sudo rmmod psmouse && sudo modprobe psmouse" doesn't help in my case. In my case I get repetively (and always) rid of this problems with log off and then log on! It seems that any stuff that is "stopped" during logoff prepares for correct mouse operation.
Note: in the case of ingoring left mouse key, sudo evtest /dev/input/event5 (5 in my case) show up response of all mouse events, but left mouse ignored by the desktop. There is no difference whether I use the mouse directly on an USB port, or via a USB/PS2-adapter pod. The mouse itself is generic simple mouse. -- 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
