Upgraded from 13.04 to 13.10 on my Ideapad Yoga yesterday, hoping it might have fixes for a couple of issues I've been having. While it seems to have made the touchscreen more usable, it has made the problem with my trackpad even worse :(

In 13.04 and below, the cursor occasionally (maybe once or twice a day) would completely stop working and to get it working again I would run

sudo modprobe -r psmouse
sudo modprobe psmouse

and it would be happy again, now every hour or so, my cursor just goes invisible, you can tell its still there as you can hover over things and they will respond. Again running

sudo modprobe -r psmouse
sudo modprobe psmouse

works but it's getting a little annoying now its so frequent!

Does anyone have any suggestions on things to try? :(

Thanks in advance!
