Please try this:

xinput --set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 280

This fix works for me! Thanks.

Hi, I want to share my xorg config to solve this problem (xinput is not the best approach ;P)

so, on /etc/X11/xorg.conf you will find something like this:

  1 Section "ServerLayout"
  2     Identifier     "X.org Configured"
  3     Screen      0  "Screen0" 0 0
  4     InputDevice    "Mouse0" "CorePointer"
  5     InputDevice    "SynapticsTouchpad" "SendCoreEvents"
  6     InputDevice    "Keyboard0" "CoreKeyboard"
  7 EndSection
(...)

Remove (or comment) line 4 and 5, also you may remove the respective Section "InputDevice"s.
You don't want this because you have /etc/X11/xorg.conf.d/10-synaptics.conf so lets add some options there, this is my configuration (I've an Acer AS1410 laptop):

  1 Section "InputClass"
  2         Identifier "SynapticsTouchPad"
  3         Driver "synaptics"
  4         MatchIsTouchpad "on"
  5         MatchDevicePath "/dev/input/mouse*"
  6         Option "TapButton1" "1"
  7         Option "TapButton2" "2"
  8         Option "TapButton3" "3"
  9         Option "EmulateTwoFingerMinZ" "50"
 10         Option "EmulateTwoFingerMinW" "10"
 11         Option "AccelFactor" "0.01"
 12         Option "MinSpeed" "1.3"
 13         Option "MaxSpeed" "1.9"
 14 EndSection

Thats all, you only need to restart X

ps: check /var/log/Xorg.0.log if something is not working

Thanks pera, this seems to be good enough to work as a permanent fix for me. It works great. However, is there still an underlying problem to solve here? Is the fact that the wrong defaults are set a problem in the kernel, or just a side effect of the configuration being incorrect on arch for our hardware? If it is just a configuration issue then I can mark the thread as solved.

After the latest Xorg release, I'm having some difficulty again. I have the same synaptics.conf as described above, but it doesn't seem to work. Scroll on the side of the touchpad doesn't work either

I haven't done the xorg update yet, as I am at work and don't want to mess up my laptop before I finish. I'll do the update tonight and see if I have the same problem, then I'll get back to you.

I have just upgraded to the latest Xorg release, and I still don't have the touchpad issue. No problems here for me, so I doubt that it is the same issue as the one we had here originally which is fixed by the above patch.

nordmoen · 2011-03-15 16:22:03

Ok, then I'm sorry for bumping this thread, thought it might have been the same issue.

I had the same issue. Uncommening community-testing and testing in pacman.conf and pacman -Syu solved that for me.
