I run Ubuntu 14.04 on a Thinkpad x201t -- 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
