Yeah, it's looking promising. I'm not quite sure yet how to integrate
it. I've managed to get it working with the standard Xorg distribution,
but not Xglamo as it require Xkb, which Xglamo doesn't currently
support. (anyone interested, I can send you pointers to what I've got
working....not quite ready though).
At a basic stage, I can define a finger gesture and map it to a
keystroke such as "a". So far the mouse events are simultaneously
passed to the underlying application. For example, passing a simple
"stroke up" will be recognized by gestikk, but also passed to the xterm
that has focus and thus will select and drag across the xterm window.
Ideally it would always be active in a smart mode. I'm thinking about
trying to restrict it such that if there is no movement after the
initial "click", than it is *not* a gesture. If there is immediate
motion, capture the entire mouse motion as a gesture and attempt not to
pass it along to the underlying application. We'll have to see how
easily this is achieved.
It may work best enabled for some apps but not others.
At worst, I'll use the AUX-key or something like that as a trigger to
enable gesture recognition.

I was running Xglamo at the time, so I had modified xorg.conf to point
to Xglamo as the display device. However, something happened that
screwed that up, both for Xglamo as well as fbdev. Right now neither
In fact, it's rather strange. If I start xinit manually after setting
TSLIB_TSDEVICE, it works:
$ export TSLIB_TSDEVICE=/dev/input/event1
$ /usr/bin/xinit /etc/X11/Xsession
However, when I run it in a fashion similar to /etc/init.d/nodm, it
$ /bin/su --login --command "/usr/bin/xinit /etc/X11/Xsession" root
This is despite putting the export command in .bashrc and verifying that
it's set. I even tried verifying that it was getting TSLIB_TSDEVICE:
$ /bin/su --login --command "printenv" root
However, it still fails to work.
I removed and then reinstalled xserver-xglamo, and the error messages
changed, but it still does not work.
