When the window system runs in 8-bit mode, it exports the same visuals that are exported by Openwindows 3.3 on other 8-bit frame buffers:
8-bit StaticGray
8-bit GrayScale
8-bit StaticColor
8-bit PseudoColor
8-bit TrueColor and
8-bit DirectColor.
Only one hardware color lookup table is available to be shared by all X11 colormaps.
In 32-bit mode, the server supports a 24-bit TrueColor visual, in addition to all of the visuals present in 8-bit mode.
When the server is started with the following option:
/usr/openwin/bin/openwin -dev /dev/fbs/cgfourteen0 defdepth 8 |
the default visual, in which the root window is created, is an 8-bit PseudoColor visual.
When the following option is used:
/usr/openwin/bin/openwin -dev /dev/fbs/cgfourteen0 defdepth 24 |
the default visual is a 24-bit TrueColor visual.
