[Bug 903236] [NEW] Touchpad incorrectly detected as PS/2 mouse on Dell Inspiron 15R N5110

 

Public bug reported:

This is likely a kernel problem, but I couldn't figure out which package
to file it against if it is.  I know others have had this bug, but I
haven't seen it reported from this hardware.

I'm on a Dell Inspiron 15R (N5110) laptop.  It says to specify the
manufacturer of the touchpad, but I can't find it.  It said "Synaptics
touchpad" in a review, and from my googlings I've seen Alps mentioned.

In any case, it's not detected as a touchpad, but as a PS/2 mouse, and
thus two finger scrolling and other multitouch features don't work.
There's no touchpad tab in System > Administration > Mouse.

I've attached the output of these commands:

$ cat /proc/bus/input/devices
$ xinput --list 
$ cat /var/log/Xorg.0.log

I'm using Ubuntu 11.10.  Here's the output of uname -a:

Linux morsan 3.0.0-14-generic #23-Ubuntu SMP Mon Nov 21 20:28:43 UTC
2011 x86_64 x86_64 x86_64 GNU/Linux
