I tryed to switch to a new Ubuntu version, but my touchpad makes troubles. I use a Dell Latitude E6520 laptop with an Alps touchpad. Currently I'm on Ubuntu 11.10.
grep -B 5 mouse /proc/bus/input/devices (under 11.10)
The touchpad works well with 11.10. Tapping and edge scrolling is going well.
I: Bus=0011 Vendor=0002 Product=0005 Version=7326
N: Name="ImPS/2 ALPS GlidePoint"
H: Handlers=mouse0 event13
When I switch to 12.04, 12.10 or 13.04 the touchpad is a bit "jumpy". I can't exactly tap buttons with the cursor. The sensivity is too high.
I tryed to modify the kernel or replace the touchpad setting, but without success
grep -B 5 mouse /proc/bus/input/devices (under > 12.04)
How can I fix this? Is there any way Ubuntu > 12.04 will recognize my touchpad like 11.10 did?
I: Bus=0011 Vendor=0002 Product=0008 Version=7326

I tryed with following, but without success (Tapping was fixed, but edge scrolling wasn't possible anymore):
Also the psmouse-alps-dkms driver didnt work for me.
sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps
