Public bug reported: I have laptops with a synaptics forcepad, and trying to use middle- button emulation on them by hitting left & right buttons is a hit-or- miss making it quite a frustrating experience.
Adding this from upstream fixes that: commit 886b5a2cd8c785e48ddf5ceb4a902cd1f518d2a9 Author: Peter Hutterer Date: Mon Apr 4 10:06:36 2016 +1000 touchpad: add a middle button software area Middle button interaction is most commonly to paste and it is a single-event interaction (button press). We provided middle button in software button mode by emulating it with a two-finger press with L+R down at the same time. This is also what many touchpads are spectacularly bad at, it is very common to detect the physical button down event before the second finger registers, resulting in left or right clicks where a middle button should be triggered. Unless the fingers are resting on the touchpad for at least one scanout, the success rate for middle button emulation is only at 70% or so. This patch adds a 25%-width middle button area between the left and the right software button, everything else stays the same. To avoid immediate breakage, the middle button emulation remains but may be removed in the future. The doc is updated to only refer to the middle button area now. https://bugs.freedesktop.org/show_bug.cgi?id=94755 ** Affects: libinput (Ubuntu) Importance: Undecided Status: New -- 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/1570282 Title: FFE: add middle button software area To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1570282/+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
