ran the gconftool set-up line, as a matter of preemptive troubleshooting
(might be a good idea to check the presence of the "decorate" plugin as
part of /usr/bin/compiz, by the way)

The problems described there indeed look like it, indeed!
fglrxinfo showed the problem immediately; the fglrx kernel driver was
*not* loaded, so GL fell back on Mesa, which produced the WSOD.
(this exchange gave me a few ideas, see #451756 )
now that I not only ran "m-a a-i fglrx-driver" but modprobed it as well
(duh), running compiz --replace yields:
GLX_EXT_texture_from_pixmap is not available with direct rendering.
GLX_EXT_texture_from_pixmap is not available with indirect rendering.
Aborting!
Manually grepping through glxinfo gives that GLX_EXT_texture_from_bitmap
is both a server and client glx extension.
running glxinfo with LIBGL_ALWAYS_INDIRECT=1 breaks with
X Error of failed request: GLXBadContext
Major opcode of failed request: 144 (GLX)
Minor opcode of failed request: 5 (X_GLXMakeCurrent)
Serial number of failed request: 16
Current serial number in output stream: 16
I suspected that the tests "-lt 3" in /usr/bin/compiz might have been
bogus; so I tried commenting out the "exit 1" there. Result:
/usr/bin/compiz.real (core) - Fatal: GLX_EXT_texture_from_pixmap is
missing
/usr/bin/compiz.real (core) - Error: Failed to manage screen: 0
/usr/bin/compiz.real (core) - Fatal: No manageable screens found on
display :0.0
Seems #451706 is probably not a bug (save for a couple more safeties,
such as refusing to run if the system appears to want to run with fglrx
but fglrx is not present and/or flgrx is here but the actual GLX
renderer is Mesa ==> White Screen of Death), but a failure of fglrx to
provide the required extensions, despite what I understood as recent
positive claims.
As a bonus, it would be good if, upon fatal exit
of /usr/bin/compiz.real, /usr/bin/compiz attempted to restart a useable
WM (might be a tricky information to grab)
Thanks
