[Bug 1550270] [NEW] Touchpad stops working randomly


You have been subscribed to a public bug:

Touchpad stops working randomly, sometimes only scroll function stops
working but mostly entire mouse freezes. Unable to move around the
desktop. Cant find anything in dmesg-, xorg- or syslog- logs that seems
to cause it. A reboot solves the problem temporarily but occures soon
again so something is borked.
