GL screensavers crash
Last modified: 2014-03-16 22:11:38 EDT
I'm not sure if this is a problem with xscreensaver or with glxMesa.
Whenever I try to use one of the GL screensavers (I tried with atlantis and
bubble3d), it segfaults. I got the following stack trace from gdb:
Program received signal SIGSEGV, Segmentation fault.
0x40032d4a in glx_send_client_info () from /usr/X11R6/lib/libGL.so.1
#0 0x40032d4a in glx_send_client_info () from /usr/X11R6/lib/libGL.so.1

I'm running XFree86-3.3.5-15 (SVGA server), Diamond Viper 330 (Riva128).
You need to add:
to your /etc/X11/XF86Config (and restart the server, of course).
Dunno how well the Riva128 is supported by the new glxMesa stuff.
(only testing here has been with G200).
Yes, the glx stuff should probably exit more gracefully
if the server module isn't there, though...
That didn't work... it caused X to crash on startup with this error:
Fatal server error:
Caught signal 4. Server aborting
When reporting a problem related to a server crash, please send
the full server output, not just the last messages
X connection to :0.0 broken (explicit kill or server shutdown).
What processor do you have?
Pentium/MMX 233 MHz.
Out of curiousity, what happens if you rebuild the SRPM
and install it on your own machine?
(that's the glxMEsa source RPM.)
Well, I rebuilt from the 19991206-3 SRPM, and I have a question regarding your
previous instructions to add:
to XF86Config. Now, this file is only in the -devel RPM. Shouldn't that go in
the main package RPM?
By the way, rebuilding the package on my machine seems to have solved the
segfault. Unfortunately, it looks like I'm not getting accelerated 3d on my
Riva128. I'm going to look into that, it looks like there is some support in
glxMesa that can be turned on.
OK, looks like the configure script is being stupid and
specifying -march=i686 when built on a PII/PIII (which
our build machine is...).
We'll get this fixed. Possibly we should build both i686
and i386 packages.
This has been fixed in the glxMesa packges, and in the
distribution as the latest Raw Hide ships with software
