I am also experiencing this since 2 days ago on my tests. I also face the same problem with the background window receiving the clicks and the front windows caring less about them.
At first I thought it was the mouse (logitech anywhere) so I changed batteries. I could move the cursor but no clicks. I even disassembled the mouse. Nothing. I then used another logitech. Same problem. It was not until I went back to 14.04 or tested on my neighbor's computer that I saw the problem. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1382845 Title: Mouse buttons are ignored To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1382845/+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
