Hi

In an Xubuntu 11.04 Wubi install on a Packard Bell Dot S2, the touchpad works perfectly if I cold boot.

But if I reboot from Windows into Xubuntu, the mouse cursor is constantly pulled to the top right corner of the screen. Trying to move the touchpad causes it to nudge slightly, but it immediately flies back to that corner.

"xinput list" gives me:
Virtual core pointer
Virtual core XTEST pointer
PS/2 mouse
AlpsPS/2 ALPS GlidePoint

"synclient -l" and "xinput list-props X" outputs are exactly the same on cold boot and reboot.

Any ideas?

Out of curiosity......

Does
lsmod | grep psmouse
return a line with psmouse in it, like this?
$ lsmod | grep psmouse
psmouse 59033 0

If so, try the following:
sudo modprobe -r psmouse
sudo modprobe psmouse

Thank you. Yes, the psmouse module is loaded and reloading it fixes the mouse problem.

What does this mean?

Not sure, but I'm guessing that something is buggy with the psmouse module in your situation (rebooting from Windows). If you want to make this permanent (so you don't have to enter these commands every time), edit the file /etc/rc.local and put the commands before "exit 0" ala:
modprobe -r psmouse
modprobe psmouse
exit 0
If that doesn't work, you'll have to throw something together to run when you login.
