Changing 24 bits to 8 bits display

larry · #1 (**permalink**) 03-04-2002

Hello all,

I was wondering if anyone can tell me how to change 24 bits depth display to 8 bits depth display for Sun Ultra1, running Solaris 8? THANKS in advance. I think that the command is ffbconfig, but it has nothing about depth.

Try this.

Code:

This is to change your 24bit display depth to 8bit
#/usr/sbin/m64config -res 1152x900x76 -depth 8 

To check your display depth try
# /usr/sbin/m64config -propt

Hope this helps, post back if you still facing the problem.

killerserv,

I'm sorry I should have stated that I have an FBB Graphic Accelerator not an M64 Graphic Accelerator. I have tried what you said but I get "No such file or directory" /dev/fbs/m640

then when I try m64config -propt i get:

# /usr/sbin/m64config -propt
m64config: /dev/fbs/m640: No such file or directory

--- OpenWindows Configuration for /dev/fbs/m648 ---
OWconfig: machine
Video Mode: 1152x900x76
Depth: 8

# exit

I'm confuess as to what this means?

ahaa.. ok i got what you mean so you having FBB Graphic card. Ok lets change the syntax:
Try this

Code:

#/usr/sbin/ffbconfig -res 1152x900x76 -depth 8

try change the value m64config to ffbconfig or fbbconfig, should be one of them depends on the type of card that you use. Give a try. Post back if that solution doesnt help.

killerserv,

Nope that did not work. I got:

# /usr/sbin/ffbconfig -res 1152x900x76 -depth 8
ffbconfig: Unknown option, -depth
ffbconfig: Unknown option, 8

I think that it has to do something with this command. But when I read the answerbook2 for this command, it doesn't says anything about setting the depth to 8bits.

Thanks
