Zspace-config

Configure a zSpace Device for CalVR in Linux

Enabling Active Stereo

• Nvidia documentation of stereo modes: /usr/share/doc/NVIDIA_GLX-1.0/README.txt
• Enable stereo:
  • sudo vi /etc/X11/xorg.conf
  • in Section "Screen": add Option "Stereo" 3
  • Create a new section like this:

Section "Extensions"
    Option "Composite" "off"
EndSection

• Run sudo nvidia-settings: verify that the refresh rate is 120 Hz
• "glxinfo -t" must show a few modes with the stereo flag set to 1
• Test with "glxgears -stereo"
• If it doesn't work, look for clues in /var/log/Xorg.0.log
