The responses were great.
But, I have some investigation to do to see what is the best solution for
the system I have been asked to fix.

Thanks to everyone for their great ideas.

I am paraphrasing these contributions.
But the first thing I was told to do is to make sure I know what the current
settings are, make sure I can telnet into the machine and su or connect a
dumb terminal to the tty port and su to root, BEFORE I try any of this. If
the new settings are wrong, I will need to go back and fix it.

Man pages for ffbconfig or m64config should be consulted.

# prtconf -F

or it might look something like this:

This shows you what adapter you4re using.

As you can see, I have an m64 adapter.

# m64config -prconf

Possible depths:  8, 24
Current resolution setting: 1280x1024x76
Current depth: 8

Also, if you run /usr/dt/bin/xwininfo, then click on the background of the
CDE display, it will tell you what you are set at.  As you can see above,
I'm at 8 bit color depth (the default).

This is great!
Look at the possible renderings I can use!

Here is the tricky part. Make sure you can go back and fix this if this
doesn't work.
Here are some tests.

# m64config -res 1152x900x76 -depth 24

# m64config -res 1024x768x77 -depth 24

Once you are happy with the results, you can always fix the file

========== cut after this line ==========


class="XSCREENCONFIG" name="SUNWm640"

========== Stop cutting at the above line ==========================

You will have to restart the X server to make it take effect. (Rebooting

WARNING (once again): Before using it, use the m64config -prconf and -propt
to make sure your hardware supports the modes shown. Failure to do so can
damage the hardware.

Thanks, everyone!

I have a user complaining about the "look" of the GUI interface and the web
browser (Netscape 4.7 for Solaris) and wants to set up the display with
something like 256 colors.
Are there some recommended settings to enhance Sun Ultra 5 and 10
running Solaris 2.8?
Another video card is right out.
And the desktop settings don't seem to deliver what he wants.

Thanks for any input.
