Some people are using SGI Octane in 8 bits per pixel mode. The TrueColor
visual is not available at this color depth on this system. If you have
such system, think of using it at its full power. I have no access to SGI
Octane, so I had no idea how to change the color depth. I would like to
thank Mr. Randal R. Ketchem for contributing the answer to this question.
<br><br>
<hr size="3">
Edit /usr/lib/X11/xdm/Xservers and change the argument list passed to
/usr/bin/X11/X.
<br><br>
e.g.
<br>
To change the default configuration from the 8-bit pseudomap
visual to the 24-bit TrueColor visual, change the single line:
<br>
:0 secure /usr/bin/X11/X -bs -nobitscale -c -pseudomap 4sight -solidroot
sgilightblue -cursorFG red -cursorBG white
<br><br>
to a single line with:
<br>
:0 secure /usr/bin/X11/X -bs -nobitscale -c -class TrueColor -depth 24
-solidroot sgilightblue -cursorFG red -cursorBG white
