Xephyr README
|
||||
=============
|
||||
|
||||
|
||||
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 nano seconds.
|
||||
|
||||
|
||||
Caveats
|
||||
=======
|
||||
|
||||
- Depth is limited to being the same as the 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.
