Thanks for the pointer. I tried to download all the source
code and recompile from the instructions found at:
http://www.x.org/wiki/Building_the_X_Window_System/
I attempted the full modular build and it breaks along the way
at xdm because of missing includes (and it's slow, purely serial
build these days?).
Right now, I'm running at 16bpp to see OpenGL apps...
Regards,
Gabriel
