Disabling the GLX visuals
The HP V
ISUALIZE
-FXE/5/10 products support the OpenGL extension to X
(GLX). If HP OpenGL is installed on anHP V
ISUALIZE
-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
DisableGlxVisuals
Screen Option to the
X*screens
file. For example:
Screen /dev/mem
