Disabling the GLX Visuals

The HP VISUALIZE-FX2/4/6 products are the first set of HP graphics devices that supports the OpenGL extension to X (GLX). If HP OpenGL is installed on an HP VISUALIZE-FX2/4/6 system, then the GLX extension offers new entry points for obtaining more information about X visuals. As part of offering extended visual information, some extra X visuals appear in the X visual list. The extra visuals are simply duplicates of visuals that would normally appear in the X visual list. In case that the extra visuals cause problems with applications, a screen option can be used to disable them.

To disable the GLX visuals, add the DisableGlxVisuals Screen Option to the X*screens file. For example:

Screen /dev/crt/

HP VISUALIZE-FX2/4/6 Colormaps

HP VISUALIZE-FX2/4/6 devices have a total of 8 hardware colormaps. Two of the colormaps are dedicated to the overlay planes, and the remaining six colormaps are dedicated to the image planes.

Of the 2 overlay colormaps, one is permanently reserved for the default colormap. The other overlay colormap is available to applications.

Of the 6 image colormaps, two are reserved for the 12-bit PseudoColor visual. The other 4 image colormaps are available for applications using other image plane visuals.

Changing the Monitor Type

A configuration tool is available to change the monitor type on HP VISUALIZE-FX2/4/6 devices. Monitor resolution, refresh rate and stereo mode settings may be configured using the setmon tool. To change the monitor type, the setmon command can be executed directly or done through the SAM system administration tool.

The setmon executable is located at /opt/graphics/common/bin/setmon. Under SAM this component is located under the top-level "Display" folder, next to the "X Server Configuration" icon.
