I managed to launch two X servers at one time, however I'm still far
from being successful. My /usr/share/gdm/defaults.conf

<snip>

[servers]
0=Standard
1=Xgl

[server-Standard]
name=Standard server
command=/usr/bin/X -audit 0
priority=0

[server-Xgl]
name=Xgl
command=/usr/bin/Xgl :1 -ac -accel glx:pbuffer -accel xv:pbuffer
flexible=true
chooser=false
handled=true
priority=0

<snip>

When entering default runlevel GDM starts and launches both servers.
First one, Standard, has got direct rendering turned on and OpenGL is
rendered by fglrx driver. OpenGL apps work fine. On the other hand
second server, Xgl, has not got direct rendering, and what is most
suspicious, it uses Mesa drivers, which cause Beryl to run at an
absolutely unacceptable performance. Why both servers are not rendered
using fglrx? Have you got any ideas how to do it?
