Package: xserver-xephyr
Version: 2:1.4.2-2
Severity: wishlist
Tags: patch
Background:
I'd like to use Xephyr to have a multiseat setup. My graphic card has
two displays and I don't know how to do differently than having one
large screen encompassing both monitors (ideally I'd have :0.0 on
first monitor and :0.1 on the second, but hey, I'm not capable). I
start Xephyr to have two X servers.
Problem:
I'd like to start one Xephyr on first monitor and one Xephyr on
second monitor. Without window manager it's a bit tricky.
Workaround:
I can use an X client that honor the -geometry option and use
the ``-parent'' option of Xephyr. It's realy ugly (but it works).
Better approach:
There is a ``-origin'' option of Xephyr that is used in PanoramiX
mode but is ignored in non-PanoramiX mode. The following patch
sets the upper-left corner of the Xephyr window to the coordinates
specified as origin if PanoramiX is not activated.
