I think there were also some configuration things
in the xorg.conf file. I thought there was one
related to the minimum pressure settings. I'll
look through my emails from 2008/2009.
I went back to the xorg.conf file I produced
and added in the various "Suppress" and "Mode"
options and now the tablet appears to work as
before.
More things to fix with the driver handling for
the wacom:
(1) work with and without an external monitor
(2) handle multiple tablets
(3) backport install support to the original os's
I've attached the updated xorg.conf file. Except
for the change in identifier names for the wacom
InputDevice types, it includes the previous configuration
as well as the new stuff.
Enjoy,
Chris
