HAL

Comment 65 for bug 337935

Ok, If I understand this correctly, you are saying that the hal
configuration file is only used for X. Gnome is controlled through
gnome-settings-demon and most of the settings are changed through gconf
or menu. You are not sure about KDE. Synclient controls extended
values. I assume these values are put in the xorg.conf file.

Under Ubuntu, if you click using two fingers, the context menu appears.
I'm not sure if that is expected behavior, that's always the way it has
worked for me. I've never used OSX so I can't comment on the clicking a
specific area.

The one thing I'm still seeing is the second finger high/low
sensitivity. Is there a setting in synclient for the
fingerhigh/fingerlow for the second finger? I can set it to 200 and the
single finger works fine and I have to press hard, but if another finger
grazes the pad, it registers. I'm thinking this is just a flat out bug.
