Bug 1088588

May need a min/max quirk patch for the kernel, too (like the ones for L440 and co). Not yet tested.

I'm pretty sure it does, otherwise a very large area at the bottom will be seen as button area and thus won't generate pointer movements if a touch starts there.

Can you please download both libevdev and libevdev-utils for your arch from here:
http://koji.fedoraproject.org/koji/buildinfo?buildID=506786

And then install them both with:
rpm -ivh libevdev*.rpm

Note it is important to use rpm -i not -U (unless you're running rawhide), so as to keep the old libevdev which is used by a lot of other apps on your system.

And then run "touchpad-edge-detector /dev/input/event#" where # is the number for your touchpad (see dmesg or Xorg.0.log) and run your finger along the outer edge of the touchpad to detect the proper min/max values. Please copy and paste the output of the program here.

Also please run the following commands and copy and paste the output here:
cat /sys/class/dmi/id/product_version
cat /sys/devices/pnp0/*/id

Thanks,

Hans

Hi Hans,

here is the information you've requested:

cat /sys/class/dmi/id/product_version:
ThinkPad L540

cat /sys/devices/pnp0/*/id:
PNP0c02
PNP0200
INT0800
PNP0103
PNP0c04
PNP0c02
PNP0b00
INT3f0d
PNP0c02
LEN0071
PNP0303
LEN2004
PNP0f13
PNP0c02
SMO1200
PNP0c31

touchpad-edge-detector /dev/input/event4:
Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event4
Move one finger around the touchpad to detect the actual edges
Kernel says:    x [1472..5112], y [1408..3834]
Touchpad sends: x [1024..5113], y [2023..4832]

Please note: x 5113 is the max value, y 2023 is the min value I got from different tries (I never could reproduce the same values for the second x and the first y value running touchpad-edge-detector).

Thank you a lot for your quick response,

Gert

Thanks,

I've started a kernel-build with a patch fixing the min/max, you can find it here:
http://koji.fedoraproject.org/koji/taskinfo?taskID=6749224

Note it is still building atm. Can you download and install it once it is finished ? After that touchpad-edge-detector should show fixed kernel values, and together with the 70-touchpad-quirks.rules change you suggested your touchpad should work properly.

Also I would like to have one bit more info from your system for future reference, can you please do:
dmesg | grep synaptics

And copy and paste the output here ?

Regards,

Hans

Thank you for the kernel build - currently everything seems to work like expected (I've build xorg-x11-drv-synaptics with mentioned changes locally). 

The output of dmesg | grep synaptics is:

[    1.313101] psmouse serio1: synaptics: Touchpad model: 1, fw: 8.1, id: 0x1e2b1, caps: 0xd001a3/0x940300/0x127c00, board id: 2722, fw id: 1484859
[    1.313105] psmouse serio1: synaptics: serio: Synaptics pass-through port at isa0060/serio1/input0

Regards,

Gert

Thanks for testing and for the input. I'm preparing an updated xorg-x11-drv-synaptics package with the necessary changes. The kernel changes are also queued-up to be picked up by the next kernel build.

Kernel 3.14.2-200.fc20 does not contain the required patch, seems like it got lost when there was the 3.14 rebase.

You're right, I've re-added it, so it will get picked up by the next kernel build. Thanks for reporting this.
