* This patch adds multiscreen support to Xephyr. For instance,
the command line : "Xephyr :4 -ac -screen 320x240 -screen 640x480"
will launch with two "screens" - namely two main windows.
The first main window represents a screen that has the number :4.0, with
a geometry of 320x240 pixels, and the second one represents a screen
that has the number :4.1 with a geometry of 640x480.
The command line: "DISPLAY=:4.1 xclock" will launch the xclock program
on the second screen, for intance.
* this patch was edited by Dodji Seketeli <dodji@openedhand.com> for:
- better style compliance with the rest of the Xephyr code
- make sure Xephyr could be launched with no -screen option. By
default that creates a default screen of 640x480 pixel like before
- display full titles on the windows - with insctructions to grab
keyboard and mouse - like before.
This was an attempt to avoid scratch gc creation and validation for paintwin
because that was expensive. This is not the case in current servers, and the
danger of failure to implement it correctly (as seen in all previous
implementations) is high enough to justify removing it. No performance
difference detected with x11perf -create -move -resize -circulate on Xvfb.
Leave the screen hooks for PaintWindow* in for now to avoid ABI change.
* configure.ac: re-sort Kdrive libs so that symbols get properly resolved.
Basically, all some libs are present in both $KDRIVE_LIBS and $XSERVER_LIBS,
and some libs orders are not correct. So I made sure Kdrive servers don't have
to link against $KDRIVE_LIBS *and* $XSERVER_LIBS. They just have to link
against $KDRIVE_LIBS now.
* hw/kdrive/*/Makefile.am: update those makefile to reflect the change in configure.ac

Composite's automatic redirection is a more general mechanism than the
ad-hoc BS machinery, so it's much prettier to implement the one in terms
of the other. Composite now wraps ChangeWindowAttributes and activates
automatic redirection for windows with backing store requested. The old
backing store infrastructure is completely gutted: ABI-visible structures
retain the function pointers, but they never get called, and all the
open-coded conditionals throughout the DIX layer to implement BS are gone.
Note that this is still not a strictly complete implementation of backing
store, since Composite will throw the bits away on unmap and therefore
WhenMapped and Always hints are equivalent.
I exported the evdev driver to Xephyr server. I'm running it using something
like:
$ ./hw/kdrive/ephyr/Xephyr :1 -mouse evdev,,device=/dev/input/event4 -keybd \
evdev,,device=/dev/input/event1,xkbmodel=abnt2,xkblayout=br
It also closes /#5668.
and the Xephyr virtual mouse keeps alive. With this patch the semantic changes
turning '-pointer' && 'Xephyr virtual mouse' always false.
Now we can open a device pointer and pass its options in Xephyr's command line
without having other pointer unused.
The former <X11/extensions/XKBsrv.h> has been pulled into the server now as
include/xkbsrv.h, and the world updated to look for it in the new place,
since it made no sense to define server API in an extension header. Any
further work along this line will need to do similar things with XKBgeom.h
and friends.
