I'll do that in another thread.

I'll try this when I get home and have a minute.  FTR, here at work,
where the screensavers work just fine, I get this:

[mhr at mhullrichter ~]$ glxinfo | grep direct
Xlib:  extension "XFree86-DRI" missing on display ":0.0".
direct rendering: No
OpenGL renderer string: Mesa GLX Indirect

(I also noticed that glxinfo is /usr/X11R6/bin/glxinfo....)

Again, later when I get home.  Thanks.
