Same problem for me since I upgraded to 12.04 in April. I can't click anything. I have to ALT+CTRL+DEL, then log out. After logging in a second time, the mouse works again.
My mouse works fine, until I use it to launch something (i.e. I can click the desktop and drag select icons, click the launcher, etc). For instance, if I launch my browser or terminal, I can no longer use the mouse*. *Sometimes I can click the bar at the top of the window (I can click the task bar area near the time, or minimize the window). My keyboard still works. I can still press the Start button on my keyboard and open the dash, and type. I just can't click properly! Is there anything like xprop or xwininfo that can tell me what has stolen my mouse? evtest still shows the mouse events - the desktop simply doesn't respond. I tried adding noapic acpi=off to grub, but then my system won't boot. Not sure if it's related, but I also experience bug 971748 on every boot. When aptd crashes, I get a windows stating "Could not grab your mouse. A malicious client may be eavesdropping on your session or you may have just clicked a menu or some application just decided to get focus." -- 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
