Buttonless Touchpads

[Chris Tyler]

Many HP (and perhaps other) laptops are now shipping with 'buttonless'
touchpads. There is a T-shaped line drawn on the pad dividing out two
'button areas' on the pad, but there is no physical button in each area.
Instead, the entire touchpad is sensitive (you can move the cursor
around even when your finger is in the 'button area') and the whole
touchpad is apparently hinged at the top and clicks a button at bottom.

Apparently the driver is supposed to:
- detect the button press and combine that with the touch position to
determine if the click should be interpreted as a left or right click
- enable multi-touch so that it can properly handle click-n-drag

However, in F14:
- a click anywhere counts as a left-click (even in the 'right-click
area')
- multi-touch doesn't seem to work (multi-finger clicks and
press-to-click-and-drag don't work)
- gpointing-device-settings can be used to enable drag lock, which helps
a bit, but no combination of settings seems to enable any click except
left-click

Questions:
- Is there a better driver (or group of settings) available?
- Is there any way to generate left- and middle-clicks on this type of
touchpad at this point in time?

(Additional info: HP model Pavillion dm1; touchpad does not show up in
'lsusb' listings (ps2 connection?)

Any help or pointers appreciated.
