The Sony Vario VGN-NR21E Notebook with ALPS Glide Touchpad is missing the right mouse click when using two or three finger tapping in Precise Pangolin 12.04.
Here is the out put of xinput list:

Any changes to synclient via TapButtonN=N seems to be ignored. When tapping with two or three fingers no right click is generated. I tried gpointing-device-settings but in vain. synclient -m 10 does not work since SHMConfig is not activated and I couldn't find any information on how to enable it without xorg.conf.

I'll be glad to do testing or provide additional information on demand.
