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. - - - 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. - - - - - -Matthew Allum <mallum@o-hand.com> 2004 - - |
