I am trying to visualize some images with Nvidia hardware stereo, but it
doesn't work. This works perfectly in my openSUSE 13.2 previously in the
same machine.

Does any body have any idea how to fix this problem?

Thanks a lot.


Hi
You need to make your modifications down in /etc/X11/xorg.conf.d so
dump that file and use a configuration file in the directory above.

For example I have a 50-nvidia.conf file containing;
Code:
cat /etc/X11/xorg.conf.d/50-nvidia.conf

Section "Device"
Identifier     "Device0"
Driver         "nvidia"
VendorName     "NVIDIA Corporation"
BoardName      "GeForce 8800 GT"
Option         "Coolbits" "5"
Option         "NoLogo" "1"
EndSection
Where are you installing the nvidia driver from?
