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 Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
