Sebastian,
Here is whats going on. I have run my VMware Windows VM lately. I ran it
after installed karmic, and all worked fine. I recently turn it back on and the
mouse won't click anywhere, and the mouse doesn't seem to track like it used
to. The messages for the VM seam to think when I move the mouse that i click in
and out of the vm.

Subject: [Bug 296610] Re: ALPS DualPoint Touchpad flaky performance
I'm confused. Which version of the patch do you run?

Status in “linux” package in Ubuntu: Confirmed
Bug description:
On a Dell Latitude E6500. Ubuntu 8.10 32bit. Out of the box, the touchpad was
almost unusably slow, taking 4 or 5 trips across the touchpad to traverse from
one edge of the screen to the other. To remedy this, I create a file:
/etc/hal/fdi/policy/shmconfig.fdi
With the following contents:
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" string="synaptics">
<merge key="input.x11_options.SHMConfig" type="string">true</merge>
</match>
</device>
</deviceinfo>
Then, I installed gsynaptics, and used System->Preferences->Touchpad to
fix most of the usability issues.
The problem now is that occasionally, the mouse will 'flip out', make
what seem to be some very fast unexpected movements, clicks, etc. When
that is done, my settings as applied by gsynaptics will no longer be in
effect - it will be back to the out-of-the-box slowness. Going back to
System->Preferences->Touchpad will now result in a error about SHMConfig
not being enabled.
To get around this, I can do 'modprobe -r psmouse; modprobe psmouse'.
After this, gsynaptics will work again, and I can go back into it and
reapply my settings. This is all a fairly big PITA, obviously. This
behavior (touchpad going nuts, needing to restart psmouse) doesn't
always happen, but seems to happen most when something intensive or
tricky is going on (e.g., it happens especially often when VMWare is
running (note: Intrepid is the host - the guest is Vista SP1). But it
happens sometimes when not running VMWare, as well. At the time when it
flips out, lots of the following can be seen in /var/log/messages:

The above is just a snippet, up to the end of the event. Nothing
interesting seems to happen at the beginning, just lots more lines like
those above.
Please let me know if I can provide you with any additional information
or try any procedures. Thank you.
