I have a laptop (Acer 7745G) with a synaptics touchpad that should support up to 3 finger multitouch if I am interpreting the output of
grep "TouchPad: buttons" /var/log/Xorg.0.log correctly. The output is below.
[ 7.805] (--) synaptics: SynPS/2 Synaptics TouchPad: buttons: left right double triple scroll-buttons
Two finger scrolling works fine but 3 finger gestures do not work in unity for some reason. I have put the following configuration in Xorg.conf.d/synaptics.conf:
Section "InputClass" Identifier "Touchpad" # required MatchIsTouchpad "yes" # required Driver "synaptics" # required Option "TapButton3" "3" Option "SHMConfig" "true" EndSection
and I have recieved the following output from synclient -m
time x y z f w l r u d m multi gl gm gr gdx gdy 48.144 5327 2456 112 3 5 0 0 0 0 0 00000000
If I am not mistaken, the 3 means it is recognizing that there are 3 fingers on the touchpad.
All of these things seem to me like they should point to Unity MultiTouch working but I cannot use any of the 3 finger multitouch gestures for some reason. I'm sure I'm missing something that should be simple but for some reason I cannot figure out what it is. Any help would be greatly appreciated.
