Reducing Color Bit depth in Centos installation

[Database Administrator]

Does anyone know where I can find information on how to lower the bit
resolution when I install centOS ? 24 bit is incompatible so I'm
trying to change it to either 16 or 32. This is too install in
virtual server 2005.

Thanks,
Pete

Inside /etc/X11/xorg.conf is a section "Screen" similar to this one:


Section "Screen"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1600x1200" "800x600"
EndSubSection
Device "Device[0]"
Identifier "Screen[0]"
Monitor "Monitor[0]"
EndSection


Change DefaultDepth and Depth to 16 and there you go.

All linux distros tend to share many characteristics.
One of those is the X config file. Either XF86config or xorg.conf

In that file is a line "DefaultColorDepth"
Change it from 24 to 16
alternatively you can start the x server with startx and force it manually
with startx -- -depth 16

*And* be sure that there is in fact a Display subsection
for "Depth 16" as is the case above where both are 24.
It can look exactly like the others, and there can be
many of them. Hence the Screen section might end up
looking like this:


Section "Screen"
DefaultDepth 16
SubSection "Display"
Depth 16
Modes "1600x1200" "800x600"
EndSubSection
SubSection "Display"
Depth 24
Modes "1600x1200" "800x600"
EndSubSection
SubSection "Display"
Depth 32
Modes "1600x1200" "800x600"
EndSubSection
Device "Device[0]"
Identifier "Screen[0]"
Monitor "Monitor[0]"
EndSection

DefaultDepth

There must also be a "Display" subsection with the line
"Depth 16" in it too.

This is why I wrote "Change DefaultDepth and Depth to 16".
