Xephyr window placement support for multiseat purposes?

[Laércio de Sousa]

I know there was a long discussion 6 years ago about adding or not a
-geometry option to Xephyr, mainly for multiseat purposes (see
https://bugs.freedesktop.org/show_bug.cgi?id=12221). Mathew Allum,
Xephyr maintainer at that time, strongly rejected the idea.

Now, 6 years later, how do you feel about it? Do you still reject the idea?

I've written a patch (needs rewrite; see
https://bugs.freedesktop.org/show_bug.cgi?id=68397), in the same
spirit of https://bugs.freedesktop.org/attachment.cgi?id=11331, that
extends the -screen option so that Xephyr can process strings like
HxW+X+Y and move its window origin to (X, Y).

In my tests, the +X+Y option is completely overriden if Xephyr is
handled by a window manager (the typical use for which it's designed
for, I guess), but it works if Xephyr is launched directly with no
window manager running, which is the case in multiseat setups.

Now that systemd-logind is available in several systems, multiseat
configuration becomes less and less painful, so I believe it's a good
time to revival those old Xephyr-based multiseat solutions.
