The user can also selectively “hide” classes of visuals. For example to suppress all visuals that don’t have an Alpha buffer and don’t have Sten- cil planes do:
Option ìSuppressGlxVisualsî ìNoAlpha & NoStencilî
The options can be white space, ampersand (&), or comma (,) delimited, and must be enclosed with a single pair of double quotes.
The following is a complete list of Glx visuals that may be suppressed
IsRgba – Suppress all visuals that are RGB (True Color).
IsCi – Suppress all visuals that are Color Indexed (Pseudo Color).
Alpha – Suppress all visuals that have Alpha planes.
NoAlpha – Suppress all visuals that don’t have Alpha planes.
Back – Suppress all visuals that have a double buffer.
NoBack – Suppress all visuals that don’t have a double buffer.
Accum - Suppress all visuals that have an accumulator.
NoAccum - Suppress all visuals that don’t have an accumulator.
Depth - Suppress all visuals that have a Z (depth) buffer.
NoDepth - Suppress all visuals that don’t have a Z (depth) buffer.
Stencil - Suppress all visuals that have Stencil planes.
NoStencil - Suppress all visuals that don’t have Stencil planes.
Stereo - Suppress all visuals that have Stereo buffers.
NoStereo - Suppress all visuals that don’t have Stereo buffers.
If an opposing pair of options is selected (for example, Stereo and NoStereo) the suppress options will be ignored since selecting an opposing pair would suppress all the visuals.
visuals suppression
This option can be used to hide whole classes of visuals. These can be selected via the SuppressVisuals option in Screen section of the XF86Config file. The visuals that can be suppressed are: PseudoColor and TrueColor. If all visuals are suppressed and no default visual has been selected, the X Server will exit with a fatal error. Also if a default visual is defined, it overrides the suppression request. The example below suppresses the PseudoColor visual. The options can be delimited by white space, , or “,”.
