Good. The X system prefers a range of values to work with,
that way it can select an optimal setting to get to the
resolution desired.
It's kind of like the difference between a simple point-n-click
camera and one that allows the modification of the shutter speed
and aperture. With the PNC camera, you're stuck with whatever
the manufacturer decided is the one single optimal settings
of the shutter speed and aperture for all conditions.
Anyway, keep those range values handy and also write down the
make and model of the video card. Jump to runlevel 3
(<ctrl><alt><f1> and log in as root and "telinit 3") and at
the command line:
1) cd /etc/X11
2) cp xorg.conf xorg.conf.orig
3) xorgconfig
It will ask about your mouse, keyboard, ... When you get to
the "horizontal" frequency step, choose "11" and enter "30-82"
and press <enter>, and for the vertical, choose '5' and then
enter "50-85" and <enter>. Dont include the quotes as I have.
For the "identifiers", use whatever words make sense to you.
Next: Do you want to look at the card database? y <enter>
Just press <enter> to find your card - if you dont find your
exact card, use one that is close or is in the same "family".
If you still feel uncomfortable, dont worry, you can copy
the original value from the saved version of xorg.conf that
are laying around in /etc/X11.
Next, specify the amount of RAM the card has.
Enter identifier names.
At the resolutions step, I usually only select the
value I want all the time, such as 1280x1024, so for
the 24-bit/16/8 resolutions, I'll only identify 1280x1024.
When you select one to change, such as '3' for 24-bit,
you'll next select a single value or a range of resolutions
you want to choose at runtime, such as "45", meaining
"1024x768" and "1280x1024". Like I said, I only select
one value for each color depth. And I answer 'no' to the
virtual screen.
Next, you'll probably choose '24 bit" for color depth
for the default. Finally, choose to write to whatever
directory you want the new xorg.conf file.
Be sure this file ends up in /etc/X11. You can change
over to this directory and use your favorite editor
to edit any other values you require. I use "joe" as
my editor - it's text based, but you can open multiple
files in it and copy values back-n-forth between files.
Now try out this new configuration:
# startx
If it starts up fine, then <ctrl><alt><backspace> to
get back to the CLI. Finally, jump back to runlevel 5:
# telinit 5
Let us know.
