-=============
-
-
-What Is It ?
-============
-
-Xephyr is a a kdrive server that outputs to a window on a pre-existing
-'host' X display. Think Xnest but with support for modern extensions
-like composite, damage and randr.
-
-Unlike Xnest which is an X proxy, i.e. limited to the
-capabilities of the host X server, Xephyr is a real X server which
-uses the host X server window as "framebuffer" via fast SHM XImages.
-
-It also has support for 'visually' debugging what the server is
-painting.
-
-
-How To Use
-==========
-
-You probably want to run like;
-
-Xephyr :1 -ac -screen 800x600 &
-
-Then set DISPLAY=:1 and run whatever X apps you like.
-
-Use 'xrandr' to change to orientation/size.
-
-There is a '-parent' switch which works just like Xnests ( for use
-with things like matchbox-nest - http://matchbox.handhelds.org ).
-
-There is also a '-host-cursor' switch to set 'cursor acceleration' -
-The host's cursor is reused. This is only really there to aid
-debugging by avoiding server paints for the cursor. Performance
-improvement is negiable.
-
-Send a SIGUSR1 to the server ( eg kill -USR1 `pidof Xephyr` ) to
-toggle the debugging mode. In this mode red rectangles are painted to
-screen areas getting painted before painting the actual content. The
-delay between this can be altered by setting a XEPHYR_PAUSE env var to
-a value in micro seconds.
-
-
-Caveats
-=======
-
- - Depth is limited to being the same as the host.
- *Update* As of 8/11/2004. Xephyr can now do 8bpp & 16bpp
- on 24bpp host.
-
- - Rotated displays are currently updated via full blits. This
- is slower than a normal oprientated display. Debug mode will
- therefor not be of much use rotated.
-
- - The '-host-cursor' cursor is static in its appearence.
-
- - The build gets a warning about 'nanosleep'. I think the various '-D'
- build flags are causing this. I havn't figured as yet how to work
- round it. It doesn't appear to break anything however.
-
- - Keyboard handling is basic but works.
-
- - Mouse button 5 probably wont work.
