This issue is happening on my 2012 MBP 13inch as well. I am dual booting OSX and Ubuntu 16.04
The issue does not manifest itself when booted into OSX - only Ubuntu. How to prevent: Remove the power connector. When removed, the trackpad works normally. How to reproduce: Plug in the power connector. After connected for several seconds, the trackpad begins to right-click randomly and/or initiate the alt-tab command. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1264795 Title: Alt+Tab Switcher randomly activates itself To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1264795/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
