How do I enable Middle mouse button emulation in 12.04 LTS? I think it was disabled by default in the last release. I'm sure this is a silly question but I can't find a generic answer, they all seem to be touchpad specific (ie, multi-touch related, which I don't have), or using what I consider not to be normal ubuntu methods (creating xorg.conf file). I'm using xubuntu variant (xfce) on a dell inspiron mini.
I was actually just testing there and if I tap with both fingers at once it brings up a context menu (like right click). Wired I didn't know this trackpad could even tell that there was a two finger tap...
Former behaviour was clicking both touchpad buttons (they are the built in kind) at the same time produced a middle clicck. They no longer do this. I never used a double tap, but the actual buttons.
To clarify I am using a built in Touchpad, not an external mouse. Gpointings detects it as synaptic touch, which I believe is correct
Update- The question @medigeek linked to below let me set a two fingered tap to emulate a middle click, but I still cant click both buttons at the same time
