I managed to disable my touchpad in KDE. I was trying the Fn key combinations to see what worked. Well Fn+left arrow which should be auto brightness popped a little message on my screen saying something about disabling touchpad, and it sure seems to have done just that. Pressing Fn+left arrow seems to do nothing now. The touchpad does work at the login screen and in LXDE. It does not appear to be disabled in system settings. I'm at a bit of a loss, I don't know where else to look. Any help would be greatly appreciated.
Thanks!
