Public bug reported: This possibly the same issue as #501942 (which has been closed to inactivity).
I have noticed the following issue after upgrading from Ubuntu 16.04 to Ubuntu 18.04: package: xserver-xorg-input-synaptics 1.9.0-1ubuntu1 After waking up from suspend, the lower left touchpad button generates "button 2" events (I checked using xev) instead of "button 1" events. To be specific, it *sometimes* generates button 1 button release events. The button above the touchpad still generate button 1 events as before sleep. The issue disappeared by itself after 40 minutes or so. It has happened on multiple occasions. ** Affects: xserver-xorg-input-synaptics (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1775598 Title: Thinkpad T530 touchpad buttons remapped after sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1775598/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
