I did but the call to XCreateWindow keeps on failing. I think 
its the call to create a drawable in the dri driver. I dont 
have the exact error message. Its in my pc at home. While 
tracing the code through gdb i got the idea of bypassing some 
things and call them directly from the glitz routines.

i see. so it opens a socket and pass the packets to the miniglx 
dispatch code. thats the code i was planning to bypass.

this leads me to a fundamental question. should the compositing 
code be in the server?

i thought that i can build myself some sort of graphics engine 
by merging glitz and sample_server or their derivatives into 
one server.

i think i have a wrong understanding of the whole architecture. 
i can see that the server and glitztest use the same GL 
library.

Yes i got that running already.
