Hi,

I recently bought a ThinkPad X250 [1]. I'm running Debian sid with the
4.0-rc4 kernel right now.

I don't use the touchpad at all, but rather the trackpoint, so I
disabled the touchpad in the BIOS. Following some advice, I setup the
input system using psmouse.proto=imps with a custom Xorg.conf.d config
file for the âtouchpadâ (the Trackpoint device disappears when using
IMPS). It works fine with xf86-input-evdev, and the psmouse module
correctly respects the BIOS setting (the touchpad itself is disabled).

Then I was made aware of that patch set and of the xf86-input-synaptics
patches [2].

I tried the patchset at [3], disabling the psmouse.proto=imps, but I
don't yet installed xf86-input-synaptics. Here are the results:

- - the trackpoint device reappears
- - the hardware buttons seem to work, and are assigned the the trackpoint
  device (and can configured using the standard trackpoint config file)
- - the touchpad is enabled, so it looks like the BIOS setting is not
  respected

So I have two questions/remarks about this:

- - if I don't use the touchpad, do I need xf86-input-synaptics at all?
- - how can I have the BIOS setting respected by the psmouse/synaptics
  kernel module (like when using psmouse)

Thanks for your patchset anyway, and regards,
