I am trying to use my Wacom Cintiq 13HD in what some call a
"ZaphodHead" configuration, i.e. where my xorg.conf file
has dual sections for Device, Screen and Monitor,
one for my regular 1600x1200 desktop display (DISPLAY=:0) and one for
the 1920x1080 display in the tablet (DISPLAY=:0.1).
Unfortunately, I have not managed to find a way in xorg.conf
to constrain the stylus range of the Wacom tablet to just one
of my two Screens (namely the DISPLAY=:0.1 one). Instead, the
stylus always travels horizontally across a 1600+1920 wide
virtual screen, which obviously breaks positioning on the tablet
display.
I just noticed that the exact functionality I was hoping for did
in fact exist in the past, in form of
Option "ScreenNo" "1"
but was removed in commit 4ffd3c64ca29a637bf1d2c69b11e360e8d8a82f5:
Author: Peter Hutterer <peter.hutte...@who-t.net> 2010-11-24 05:02:15
Purge ScreenNo handling.
The definition of ScreenNo isn't clear, given that we have RandR
screens,
ScreenRecs and protocol screens, not all of which overlap totally. Let the
mapping of the tablet to a given area on the available desktop be handled
by
a client.
That removed option seemed to do exactly what I wanted (for
protocol screens) ... :-(
Is there now any other way in /etc/X11/xorg.conf.d/ (or a similar
global config file) to bind the absolute coordinate range of a wacom
tablet to just one single screen?
I would very much like this binding between screen and tablet
to be done properly from the very beginning by the X server,
in a system-wide configuration file for all users (like xorg.conf),
before the user logs into a display manager. I therefore would
like to avoid user clients such as "xsetwacom set 14 MapToOutput ..."
that only kick in after login.
Is there no chance to bring Option "ScreenNo" back,
perhaps with a slightly changed syntax to make the
semantics unambiguous?
What was gained be dropping the existing multi-head support
from the driver?
