Hi,
Sorry if I misposted this message. If it is the case please forward it
to the appropriate people.
I've recently installed the modules required for dri support for my
video card (mach64LB chipset) and that forced me to replace the
/usr/bin/X11/XFree86 executable which came from the debian package
xserver-xfree86 4.1.0-16 with one corresponding to the 4.2.0 release
provided by dri.sourceforge.net
I've managed to setup dri but things are a little messy at startup.
Indeed, what happens is that if I try to log in with xdm (which is
started automatically), things fail. To get things to work, I need to
log in as root in tty1 for example dans restart (?) xdm with:
>xdm
After that the log in process runs more smoothly and I can start a
session as a normal user.
Here is an excerpt from my /var/log/XFree86.0.log file:

OK, that's one thing. I have another problem related to the content of
my DISPLAY variable. If it points to the local one (ie: DISPLAY=:0.0)
things work just fine but if I change it to DISPLAY=`hostname`:0.0 then
nothing ever pops up on my screen. The consequence of this is that I
cannot export windows to my screen when log in some other machine of my
LAN.
To summarize things a little, I really do not understand much about how
X handles security and allows users/processes to access to different
resources. Is there a well structured relatively simple and readable
documentation somewhere ?
Thanks a lot for your help.
