I'm also on Thinkpad T520 with Ubuntu x64 15.04. I tend to use an external Logitech M705 mouse with a Unifying Receiver -- but the Logitech might just be a casualty.
This was not a problem until I moved to 15.04 -- I did a bare-metal install to eliminate system cruft, but retained the home partition. I'll try to file a report when the problem recurs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1316873 Title: Left mouse button stops working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1316873/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
