How do I get X going as well as xvidtune

Yes. You can switch resolutions on the fly with CNTL-ALT-+, that's
the control, alt, and plus key all at the same time. You can also
change which resolution comes up first by default.
There is a section of the /etc/X11/XF86Config file that looks like
# The accelerated servers (S3, Mach32, Mach8, 8514, P9000, AGX, W32, Mach64
# I128, and S3V)
Device "My Video Card"
Monitor "Sony CPD-17SF2"
Modes "1280x1024" "1600x1200" "640x480" "1024x768"
ViewPort 0 0
Modes "1600x1200" "1280x1024" "1024x768" "640x480"
ViewPort 0 0
Modes "640x480" "1024x768" "1280x1024" "1600x1200"
ViewPort 0 0
For each Display subsection, go to the Modes line and list the
resolution you like first.
Most of the time, people select this through a graphical configuration
tool. See if you can run the command "XF86Setup", as root, without X
and KDE running, and set the configuration you like. Then use the
xvidtune for the fine-tuning.
Once you have X (by this I mean KDE, your entire desktop) starting up
in the right resolution, go through the steps of running xvidtune and
getting a Modeline and putting it in the /etc/X11/XF86Config file.
Michael> Did that. There is a warning msg. that pops up. In what way

It used to be the case that some monitors could be permanently damaged
by being run at the wrong hsync and vsync frequencies, or something.
I believe that most modern monitors have some sort of chip controller
in them and they will protect themselves. It is probably not
something you have to worry about.

You can just open a text terminal right there in KDE, and use su to be
root in that terminal, and that way you can cut-and-paste the modeline
numbers without having to write them down.

As I explained above, you need to switch X into the 1024x768
resolution and then generate a new modeline.
As a side note, is there a reason you prefer the lower resolution ?
I've had monitors that were kind of flickery at the highest
resolution, but if you are doing it because you don't like X to have a
virtual desktop so that you use the mouse to pan around and see
everything, then there is some way to turn that off and keep the same
Michael> Excuse me for asking for more details. I am new to linux.
No problem, that's what this group is for. Restart X the same way you
always get to a KDE environment; usually it is the command "startx".
