What are the differences between the X server named "X" and Xsun?
We have an application (written in Franz Inc's implementation of Common
Windows) that works fine when we start X up with a simple "xinit", but
exhibits poor behavior when started with "xinit -- XSun ..." (when
popup menus are dismissed, the underlying region isn't refreshed,
etc.). I'm told it has something to do with "X" being a "backing
server"(?).
Also, I'd like to run suntools on the color planes of my 3/110 and X on
the b&w overlay plane, but the "X" server seems to take over both sets
of bit planes (Xsun can be told not to, of course, but then I can't run
the above application).
I've RTFM, but I don't see if it's possible to either (a) get "X" not
to take over all the bit planes, or (b) get "Xsun" to act as a "backing
server", if that's the right terminology.
Thanks,
Mike Khaw

> What are the differences between the X server named "X" and Xsun? On a Sun, nothing. The build gives separate names to each server binary (e.g. Xsun, Xqvss, Xhp, etc.) so that you can compile any number of servers (for different graphics devices or for building test servers like Xndx) at a time. If you use the xinit program to start your server, you need to either tell it the name of the server program explicitly (e.g. xinit -- /usr/bin/X11/Xsun :0) or create a link (or script) named "X" somewhere in your path pointing to the right server. > We have an application that works fine when we start X up with a simple > "xinit", but exhibits poor behavior when started with "xinit -- XSun ..." > (when popup menus are dismissed, the underlying region isn't refreshed, > etc.). I'm told it has something to do with "X" being a "backing server"(?). It sounds like somebody left an old server lying around. The Release 3 server automatically supports backing store unless the server is started with the -bs option. Jim Fulton MIT X Consortium
