NAME
Xephyr - X server outputting to a window on a pre-existing X displaySYNOPSIS
Xephyr [:display] [option R ... ]DESCRIPTION
Xephyr is 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.

SIGNALS
Send a SIGUSR1 to the server (e.g. pkill -USR1 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
- Rotated displays are currently updated via full blits. This is slower than a normal orientated display. Debug mode will therefore not be of much use rotated.
- The -host-cursor cursor is static in its appearance.
- The build gets a warning about nanosleep. I think the various -D build flags are causing this. I have not figured as yet how to work round it. It does not appear to break anything however.
- Keyboard handling is basic but works.
- Mouse button 5 probably wont work.
