Rod,

I think you may have invalid mode lines.  The most standard dimensions
you should have for a "regular" monitor are more along these lines:

        640x480
        800x600
        1024x768
        1280x1024
        1400x1050
        1600x1200

I realize this may not help your problem except that if you define your
modeline incorrectly and say that you have only 1600x1024 when you
should be saying 1600x1200, you can see that your screen might be
missing something!

Hope this helps.


Dave

Subject: [Newbie]1600x1024 resolution cuts off bottom

I've just upgraded from Red Hat 7.3 to 8.0, which took me from XFree86
4.1
to 4.2.0.  The XF86Config file built by Red Hat no longer includes any
explicit modelines, and there is no default entry for 1600x1024
resolution,
so I pasted my old modeline into the Monitors section.  Everything
displays well except that the bottom half-inch of the screen is cut off.
(It worked fine in 7.3.  Why would it change?)  Fiddling with the
monitor
controls shows that the signal really is cut off.  I've tried monkeying 
around
with the modeline using xvidtune, to no avail.

But... When I use KDE's control center app, under Information -> X
Server,
I find a line saying
"Dimensions    1600 x 1050 Pixel (484 x 310 mm)"
which certainly suggests that somewhere in all this X machinery there is
something telling the X server that I want resolution 1600x1050, not
1600x1024!

Can anyone suggest a fix?  I don't know where to go from here.

Thanks,
