HP VISUALIZE-FXE/5/10 Configuration Hints

Overlay Visuals and Overlay Transparency

HP VISUALIZE-FXE/5/10 devices have two visuals in the overlay planes, both depth-8 PseudoColor. The first (default) overlay visual has 256 entries per colormap and no transparency. The second overlay visual has 255 entries per colormap and supports transparency.

To allow applications to determine which visuals are in the overlay planes, both overlay visuals are listed in the SERVER_OVERLAY_VISUALS property attached to the root window. The default overlay visual has a transparent type of "0" (None), while the transparent overlay visual has a transparent type of "1" (TransparentPixel).

If you need an overlay colormap that supports transparency, create the colormap using the visual that has transparency in its SERVER_OVERLAY_VISUALS property.

Disabling the GLX Visuals

The HP VISUALIZE-FXE/5/10 products support the OpenGL extension to X (GLX). If HP OpenGL is installed on anHP VISUALIZE-FXE/5/10 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 DisableGlxVisualsScreen Option to the X*screens file.For example:

Screen /dev/crt/
