A few pieces of code were abusing this define for other purposes, which are converted to #ifndef DEBUG instead. There should be no ABI consequences to this change. The rationale is that having the define in xorg-server.h also disables assert() drivers, which is unexpected, and also difficult to avoid since xorg-server.h is included in their config.h, and you can't put a #undef in config.h. As for removing it from the server instead of moving it to an internal header, we probably shouldn't have unnecessary assert()s in critical server paths anyway, and if we do we could #define NDEBUG in the specific cases needed. |

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