[ubuntu] [UX31] Elantech touchpad multitouch stops working for no reason

view story

http://ubuntuforums.org – Hey, I'm using the UX31 with the latest Ubuntu (12.10) and my elantech touchpad's multitouch supports seems to break after some unidentified event. I'm not going to sleep, just using the laptop and then, bam scrolling with two fingers no longer works, also mid/right click by finger tapping also. I don't know what is causing this, it was happening in 12.04 as well, just less often. Now it's very frequent (and very annoying). What can cause this? Where can I report it? Anyone else experience this? Thanks. (Hardware)
