Supposed I had one already (or more generally:
something with
touchscreen), what would it require to get ardour, pd and stuff like
that to work with the touch screen? IOW: what happens when you touch the
screen, and where is X in all this?
Touchscreens are actually quite easy. Assuming that your X is Xorg, you
just need to build X with the appropriate driver for your touchscreen
(Microtouch, or whatever), then add in appropriate configuration.
Touchscreens are pointing devices, just like mice, and may be used in
conjunction with one. (Actually they are more like graphics tablets in
that positioning is absolute rather than relative.)
I would suggest that you choose a touch screen and then Google for
something like this:
<http://www.google.com/search?q=xorg+microtouch> (Assuming a Microtouch
driver.)
You can get a Debian package for the Microtouch driver, Gentoo (what I
use) just needs USE=input_devices_microtouch when building xorg-server
and I guess the other distributions will have similar facilities.
The only caveat would be if you were to choose a touch screen that did
not have an Xorg driver.
Once you've got a driver, there should be no shortage of xorg.conf
examples available out there to help you get it set up.
Personally, I have had my share of trying to clean finger-marks off
screens and now use an ergonomic optical trackball! (Seem to recall
reading an article on Tangerine Dream - trackball users due to them
being pretty stable in a stage environment.)
Hope this helps.
Cheers
