I found a solution! At least for my case. I have a 2015 MacBook Pro with Ubuntu 16.04 LTS.
According to these: https://askubuntu.com/questions/456299/state-of-multitouch-gestures-in-14-04-unity https://wiki.ubuntu.com/Multitouch This happens, because sometimes the touchpad's 3 finger tap followed by 3 fingers hold is triggered randomly. You can disable this, by overwriting the TapButton3 option in synclient. Just like this doc says: https://wiki.ubuntu.com/Multitouch/TouchpadSupport I set it to behave like a middle mouse click (which is more handy because if you select/copy some text then 3 finger tap, it behaves like a paste in input fields). Here is an Ask Ubuntu post that explains the process: https://askubuntu.com/a/156545/323990 In short: echo synclient TapButton3=2 > ~/.config/touchpad_settings chmod +x ~/.config/touchpad_settings Then run this script at startup. Searching for "Startup Applications" in the dash then add a new startup program with the command: "/home/your-user-name-here/.config/touchpad_settings". Don't forget to replace the "your-user-name-here" part in the path with your username. -- 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
