Xephyr, DRI, and compiz

[Yan Seiner]

I am trying to get Xephyr running with compiz.  The following was
generated with xserver 1.5.0 and xephyr 1.5.0.  I've had the same results
with 1.5.1.

glxinfo tells me that DRI is not available.

and when I try to compiz I get

Checking for Xgl: not present.
xset q doesn't reveal the location of the log file. Using fallback
/var/log/Xorg.0.log
Detected PCI ID for VGA:
Checking for texture_from_pixmap: present.
Checking for non power of two support: present.
Checking for Composite extension: present.
Comparing resolution (640x480) to maximum 3D texture size (2048): Passed.
Checking for nVidia: not present.
Checking for FBConfig: present.
Checking for Xgl: not present.
/usr/bin/compiz.real (core) - Fatal: Root visual is not a GL visual
/usr/bin/compiz.real (core) - Error: Failed to manage screen: 0
/usr/bin/compiz.real (core) - Fatal: No manageable screens found on

So what can I do to diagnose this?  What,if anything, can I do to get
compiz running on Xephyr?

As long as nobody gets hurt, a decent explosion livens up any experiment.
