After successfully re-configuring your monitor, the X Server will be
restarted.
If you are configuring a Visualize fx display proceed to you can verify
the availability of GLX stereo visuals now by running the xglinfo
command again.
If you are configuring a FireGL graphics device an additional step is
required. Run "sam" to configure stereo mode in the
/etc/X11/XF86Config file. Select the "Display" area and the "X Server
Configuration" then select the display device icon. Using the Actions
menu select "Modify Screen Options". This dialog box will the allow
you to select and set to "true" the "Stereo" option (for FireGL X1/X3)
or "Qbs" (e.g. Quad-buffer stereo) option (for the FireGL-UX) . Once
this option is set and the configuration is saved the X server can be
restarted and will be in Stereo mode.
3. To select one of the stereo capable GLX visuals through OpenGL, the
GLX_STEREO enumerated type should be passed to either
glXChooseVisual() or glXGetConfig(). Once a stereo visual has
been selected, it can be used to create a stereo window, and
glDrawBuffer() can then be called to utilize both the right and left
buffers for rendering stereo images.
