hp Fire GL-UX configuration hints
This may cause problems with some applications. Setting "CountTransI- nOvlyVis" causes the server to reserve the transparent pixel index. In this case, the server reports that 255 colormap entries are available for allocation in the PseudoColor visual. This option may be useful to appli- cations that depend on having 256 colormap entries available in depth 8 PseudoColor visuals. The transparent index value is configurable through the "TransparentIndex0" device option. Setting this option will change the transparent pixel value to 0 from the default of 255. This option may be useful to applications that depend on the transparent pixel value being 0.
HP Fire GL-UX Colormaps Hints
HP Fire GL-UX devices have a total of 5 hardware colormaps. One color- map is reserved for gamma correction and is not directly available to X clients. The remaining colormaps are available for clients to use. When the default visual is in the overlay planes, one of the four available hard- ware colormaps is reserved for the default colormap. This ensures that clients using the default colormap never encounter technicolor.
The HP Fire GL-UX driver reports on the installation status of a total of 5 colormaps via the XListInstalledColormaps() API. Four of these corre- spond to the actual state of the hardware color tables used with Pseudo- Color visuals. Colormaps are installed in these hardware LUTs in first-in, first-out order. The driver also keeps track of the last TrueColor colormap installed via XInstallColormap() and includes this information whenever queried. By definition, all TrueColor colormaps are always installed.
