Hi,

Sounds line you didn't have a correct installation of the Xig summit2.2??? I thought the installation was supposed to move all the old mesa/GL stugff to a back up and replace them with
the acellerated xig ones?

Have you contacted the guys at Xig?
If you have paid the 99 dollars or whatever it costs,
then their support is usually prompt and effective!

Lack of DRI means your graphics hardware is not being used at full speed!

On my RH8.0 box, the radeon 8500 64MB with Xig summit 2.2 is working really well for quad buffered stereo.
Haven't are upgrade to RH9 yet..... I keep hearing about problems!

cheers

Dan

Subject: [PyMOL] 2 questions about Summit drivers w/ Radeon8500 card for stereo...

Dear PyMOL and O list members,

I just got stereo working on my machine (PC, Red Hat 9, Radeon8500
(64MB) video card) after installing Xi Graphic's Summit v2.2 DX-Platinum
drivers to enable quad-buffered software stereo, but I noticed that 3D
stereo rendering in 'PyMOL' and 'O' seems a lot slower than it used to
be (same hardware, but w/ Mandrake and v2.1 Summit drivers). So, I have
2 questions (that may or may not be related to the sluggishness):

(1) After installing xvsc and summit drivers, is any further
configuration required to insure proper usage of the Accelerated-X
openGL libraries, include files, etc.? I ask this because I noticed that
GL-based programs such as PyMOL are NOT using the Accelerated-X library
"libXda.so.1"...
For example, if I type "ldd /usr/X11R6/bin/xglinfo" I get the following:

[r...@cm1 etc]# ldd /usr/X11R6/bin/xglinfo
        libGLU.so.1 => /usr/lib/libGLU.so.1 (0x4002d000)
        libGL.so.1 => /usr/X11R6/lib/sav-GL/libGL.so.1 (0x400b2000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40125000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40134000)
        libm.so.6 => /lib/tls/libm.so.6 (0x40213000)
        libc.so.6 => /lib/tls/libc.so.6 (0x42000000)
        libpthread.so.0 => /lib/tls/libpthread.so.0 (0x40235000)
        libdl.so.2 => /lib/libdl.so.2 (0x40243000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

I guess I could remove the paths to the old mesa GL libraries and
include files ("/usr/include/GL/sav-GLinc/" and
"/usr/X11R6/lib/sav-GL/") from /etc/ld.so.conf, but then other GL-based
applications don't seem to work?? So, is there anything special i need
to do in order to make the "libXda.so.1" module used instead of the
standard Mesa openGL ones???

(2) Upon start-up, GL-based applications give the following line:
       "Xlib:  extension "XFree86-DRI" missing on display ":0.0".
I'm wondering what this problem means (if anything), and how it may be
corrected??

Thanks for any advice!
     Cameron
