It happened to me today, and after trying a few modprobes, I finally got my left/right clicks and mouse wheel back thanks to xev. I launched it in a terminal and tried some random mouse actions until it worked again. I have no idea whether or not the previous modprobes have an impact on this.
I attached the output of xev, in cas it can be useful. ** Attachment added: "xev.txt" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-mouse/+bug/828893/+attachment/2305720/+files/xev.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-mouse in Ubuntu. https://bugs.launchpad.net/bugs/828893 Title: left mouse button ignored To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-mouse/+bug/828893/+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
