Description linux4fun 2010-07-19 21:40:17 UTC
Description of problem:
The trackpad of Dell Precision M4500 is not recognized as such, but instead, as a PS/2 Generic Mouse, thus it is not possible to use scrolling ...

Version-Release number of selected component (if applicable):
Might be linked to Bug #590880 however I do not have the technical knowledge to make the checks, debug the module and retrieve the device code.

How reproducible:

Actual results:
The trackpad and track stick have basic mouse functionalities and are not
visible via synclient.

Additional info:
# synclient -l
Couldn't find synaptics properties. No synaptics driver loaded?
# grep ALPS  /var/log/Xorg.0.log
(nothing found)

That patch is not even in input.git yet.

I've just applied the patch referenced in comment #2 to kernel-, and it works fine for me on my DELL Precision M4500, enabling the scrolling functions.

Comment 4 Alex Tucker 2010-09-09 20:39:03 UTC
Having said that, and now having gone through a suspend/resume cycle, the mouse pointer went crazy on resume, so I don't think it's quite there yet.
