It seems Unity is not affected. I took some time to respond because I could not reproduce the bug yesterday after rebooting the machine. It seems something triggers the bug, and once it has been triggered I can consistently reproduce it with pm-suspend, even after logging out and back in (this in itself makes the issue disappear, but suspending makes it appear again).
So now that it occurred again, I logged several times into Unity and Gnome Shell (xorg), and executing pm-suspend always made the problem appear in Gnome Shell, and never did in Unity. I still do not know what triggers the bug in the first place, but it seems to occur usually when I go from work to home or vice versa, which implies suspending, closing the lid, unplugging the AC adapter, external monitor and USB hub. For what it's worth, the problem occurs with my USB mouse and with my Bluetooth mouse. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libinput in Ubuntu. https://bugs.launchpad.net/bugs/1752709 Title: Left mouse button gets stuck down (in software), usually after suspend/resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1752709/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : email@example.com Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
