after this update, somehow the touchpad stopped responding; the left- and right-click buttons are working properly, however. i reinstalled libinput, and it started responding, but only for a few minutes, and then stopped working once again.
And now, it is working again after about 5 minutes of unresponsiveness. Any ideas?
Edit : and now it has stopped responding once again. This is getting seriously annoying.
p.s. : i am on KDE running linux 4.19.1
