I can confirm this issue on a Thinkpad T420, both on a freshly installed Ubuntu 14.10 and Kubuntu 14.10.
It first occured shortly (but not immediately) after enabling the touchpad in the bios. Reinstalling the system or running from a live usb did not fix it. After disabling the touchpad again in the bios, the problem was gone immediately. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/41301 Title: PS/2 Logitech MX310 clicks stop working sporadically To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/41301/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
