Note that the TurboVNC Helper in the evolving TurboVNC 3.0 code base has
been upgraded to use X Input v2, but that necessitated (at least
temporarily) limiting support to Wacom devices. The issue is that, in X
Input v2, the extended pointer device type (stylus, eraser, pad, touch,
etc.) can only be obtained using driver-specific X Input properties, so
supporting non-Wacom devices will require determining how to obtain the
device type for those devices. It was unclear whether non-Wacom extended
pointer devices worked with TurboVNC 2.2.x anyhow, and I am unaware that
anyone has ever tested that. It's entirely possible that they never did.
To make a long story short, I can probably support any extended pointer
device (minus multi-touch support, which is a horse of a different color)
in the Linux TurboVNC Viewer as long as I can get access to the device (or
funding to purchase one) and funding for my labor to test it and implement
support for it.
