If the composite extension is enabled in xorg.conf, xscreensaver crashes while
using any glx screensaver from rss-glx.
Steps to reproduce
1. Enable composite extension in xorg.conf
2. Restart X
4. Choose any glx screensaver eg. Helios and hit preview
5. Expected result is working screensaver.
6. Actual result is that the screensaver segfaults.
System: x86 Gentoo linux kernel 2.4.25
Graphics card: nvidia geforce3
xscreensaver version: 4.16
rss-glx version: 0.7.6 (http://rss-glx.sf.net)
did you try the same thing with xscreensaver 4.18 ?
if not, do :
then, retry to launch a GL based screensaver
btw, which xorg version did you use ?
6.7.0, 6.8.0 or a RC like 184.108.40.2064 ? (if not 6.8.0, do "emerge sync ;
USE="-dlloader" emerge xorg-x11" before emerging newer xscreensaver)
I'm using xorg 6.8.0 at the moment.
The weird thing is that whenever I try and start a gl screensaver, it fails.
But, I walked away from the computer for a few minutes only to see that it was
actually running! Then it stopped working again. I'm going to try
xscreensaver-4.18 right now, and see if that works.
The error that 4.16 gives me follows. Don't know if that will help.

Well, this turned out to be a xscreensaver problem and not an xorg problem.
xscreensaver was not using glx at compile time, and i had to manually put in
--with-gl in the configure. Anyway, it works properly with xscreensaver-4.18
