I'm using Ubuntu 12.10 on my MSI X460DX notebook for a few weeks. Touchpad worked without problem. 2-finger scrolling worked as well as disabling touchpad with key shortcut. But now after a restart touchpad just stopped working completely. System Settings->Mouse and Touchpad->Touchpad tab was not here So I tried to run sudo modprobe psmouse and than it started working, but the touchpad settings still aren't here and neither edge scrolling nor 2-finger scrolling is working. I also can't disable it. I found out, that the touchpad is recognized as PS/2 Generic Mouse instead of my elantech touchpad.

    ↳ AT Translated Set 2 keyboard              id=12   [slave  keyboard (3)]

Is there a way how can I get my touchpad working properly as before?

Same issue on Kubuntu. Just restarted my Dell after 30+ days. 1. Touchpad does work, but tapping on it doesn't register as a click which it did before. 2. Trying to open the touchpad settings crashes the settings app. –  Dror Jan 16 '13 at 22:55

I found the solution! I found it here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/667707 and a workaround from comment #3 worked.

sudo rmmod psmouse
sudo insmod /lib/modules/`uname -r`/kernel/drivers/input/mouse/psmouse.ko
