Subject: ephyr: set screen size & origin from host X server output's CRTC
geometry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If a given output is passed via new -output option, Xephyr will query
host X server for its info. If the following conditions are met:
a. RandR extension is enabled in host X server;
b. supported RandR version in host X server is 1.2 or newer;
c. the given output name is valid;
d. the given output is connected;
then Xephyr will get output's CRTC geometry and use it to set its own
screen size and origin. It's just like starting Xephyr in fullscreen mode,
but restricted to the given output's CRTC geometry (fake "Zaphod mode").
This is the main feature needed for Xephyr-based single-card multiseat
setups where we don't have separate screens to start Xephyr in fullscreen
mode safely.

Subject: ephyr: enable screen window placement following kdrive -screen option
extended syntax
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
With this patch, one can launch Xephyr with option "-screen WxH+X+Y"
to place its window origin at (X,Y). This patch relies on a previous
one that extends kdrive -screen option syntax to parse +X+Y substring
as expected.
If +X+Y is not passed in -screen argument string, let the WM place
the window for us, as before.

Subject: kdrive: add support to +X+Y syntax in -screen option parsing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch enhances current -screen option parsing for kdrive-based
applications. It can parse strings like
<WIDTH>x<HEIGHT>+<XOFFSET>+<YOFFSET>, storing X and Y offsets
in KdScreenInfo instances.
For negative values, this patch supports +-X+-Y (not -X-Y) syntax.
It will allow e.g. proper Xephyr window placement for multiseat
purposes.
