Thanks to both of you, it works fairly well on my Acer Aspire 5551 laptop with Synaptics 7.2 firmware.
What's the prefered method of configuration? xorg.conf/synclient or xinput? I use the following from .xintrc/.xsession: synclient TapButton1=1 synclient TapButton2=2 synclient TapButton3=3 synclient VertEdgeScroll=1 synclient VertTwoFingerScroll=0 syndaemon -d -t -K The sensitivity is a bit high for tap-to-click though, especially for buttons 2 and 3.. for bringing up cwm menu's, etc. It's still something that has been missing for a long time, the physical buttons are annoying to use on my laptop.. fortunately button 1 was implemented in the firmware (..and hence worked with xf86-input-mouse). -Bryan.
