Hi thanks for forwarding Peter Wolanins email about working stereo on
linux with the latest driver from nvdidia on a Geforce2. I have some
problems getting the same working on a geforce3 with Mandrake linux 8.1
kernel version 2.4.8-26mdk .
I successfully installed the latest driver 31.23 using the appropriate
precompiled binary rpm from the nvidia website. After installation Made
sure that the application gears was working fine and that the installation
was using the right libraries , also pymol works fine . Now I added the
Option "Stereo" "1"
Line in the config file as suggested in the email and hinted in the
README ,And restarted X
Howvever pymol responds saying that Stereo support is not available. Also
the XFree86.0.log (for version Xfree version 4.1.0)says
that stereo is available only on Quadro cards
(**) NVIDIA(0): Option "Stereo" "1"
(**) NVIDIA(0): DDC stereo requested
AND LATER DOWN in the log IT SAYS
(II) Module ramdac: vendor="The XFree86 Project"
compiled for 4.1.0, module version = 0.1.0
ABI class: XFree86 Video Driver, version 0.4
(WW) NVIDIA(0): Stereo is only available on Quadro cards
The readme from nvidia also says that stereo is supported only on quadro
cards.
Just wondering whether any other "fix" is required to enable stereo on my
geforce3 assuming that the geforce3 like the geforce2 is not a quadro
based card.
I know that previously there were products like softquadro ( for
PC-win2000)that patched the nvidia driver to fool it into thinking we have
a quadro (Incidentally thats the solution i use to get pymol stereo under
windows on the same machine)
Any help to get this working ,will be greatly appreciated..
Thanks
Hari
