Bug Description

Binary package hint: kdebase-workspace

After upgrading to Kubuntu Lucid I tried to use the touchpad configurator in KDE settings, but it was greyed out.

The configurator reports the touchpad as being "AlpsPS/2 ALPS".

the device is listed as "AlpsPS/2 ALPS DualPoint TouchPad" in /sys/devices/platform/i8042/serio1/input/input6/name.

I have the same symptoms, plus the ones described in bug 123775.

Could you check whether you have them too, by executing the following 2 steps?

1) Execute "cat /proc/bus/input/devices" and see whether your touchpad is detected as "ImPS/2 Generic Wheel Mouse". In
my case it looks like this:

....

I: Bus=0011 Vendor=0002 Product=0005 Version=0000
N: Name="ImPS/2 Generic Wheel Mouse"
P: Phys=isa0060/serio2/input0
S: Sysfs=/devices/platform/i8042/serio2/input/input8
U: Uniq=
H: Handlers=mouse3 event8
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=103

...

2) Execute "sudo tpconfig -i" - does it detect a Synaptics Touchpad?

In my case the output is:

$ sudo tpconfig -i
Found Synaptics Touchpad.
Firmware: 8.96 (multiple-byte mode).
Sensor type: unknown (0).
Geometry: rectangular/landscape/up.
Packets: absolute, 80 packets per second.
Corner taps disabled; no tap gestures.
Edge motion: none.
Z threshold: 6 of 7.
2 button mode; corner tap is right button click.

My machine is a Sony Vaio VPCEB1M1E laptop:

Initially, I thought that my problem is the same that in bug 512192, but patches for psmouse kernel module provided there don't help me.

There is a possible fix (patch against the kernel which needs some adjustments for the given hardware model) in bug 377741.

Please test whether it works for you.

After upgrading to Kubuntu Natty, I no longer have the problem.

The KDE Input Settings/Touchpad KControl Module (which seems largely redesigned) allows reconfiguration and correctly reports the device as AlpsPS/2 ALPS GlidePoint.

This is on a Sony Vaio VPCEB1M1E laptop.
