Hypothesis verified using "xinput list":
p...@debian-gta02:~$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ s3c2410 TouchScreen id=6 [slave pointer (2)]
⎜ ↳ "s3c2410 TouchScreen" id=8 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ "PCF50633 PMU events" id=7 [slave keyboard (3)]
↳ "Neo1973 Buttons" id=9 [slave keyboard (3)]
See the two "TouchScreen"?
Double quoted devices are those originating from udev.
I've asked #debian-x and the answer is that this behavior *is* normal
and there is currently no way to set options via xorg.conf to an
InputDevice originating from udev. More will be possible with Xorg
1.8[1]. Meanwhile, any option to such an input device should be set
using "xinput set-prop".
To sum it up:
* xserver-xorg-input-tslib misses a udev rules file to supersede evdev
for the touchscreens it can handle;
* don't set any InputDevice section in xorg.conf for input devices
already detected by udev, or you'll end up with multiple input devices
competing.
Thanks,
