Well, I /did/ say "FWIW", "for what it's worth".  If
it's not found to be 
"worth" anything to the OP, it can be simply ignored,
thus the FWIW in 
the first place.  But see below.

I thought it a worthwhile suggestion, because:

1) The poster indicated more windows space (thus a
higher resolution) 
might be useful.

2) The 1280x1024 that is claimed as the largest specs
size is, as you 
point out, squished (non-square pixels, which I
mentioned as well, as 
square pixels for 1280x960).

3) Given those specs (as well as the OP's own words),
the monitor is 
likely entirely incapable of even 70 Hz refresh at
the 85 Hz you claim 
for 1280x1024, or even the 70 Hz the OP stated he
wanted.  Do the math or 
plug in the numbers in your own modeline generator if
you doubt.  That's 
why Cola's yielded only a 70 Hz refresh at 1280x960,
instead of ~87 or 
so, as should be possible at 960p if it can do 1024
at the 85 you 
suggested.  (Cola's generator deliberately uses
slightly loose timings 
parameters tho, but there's a spot to set tighter
tolerances if you 
believe your hardware can handle it, but it still
wouldn't hit anything 
like 85 Hz and probably not even the 70 Hz mentioned
by the OP as that's 
the specific reason he gave for choosing 1024x768,
that he was able to 
get 70+ Hz refresh that way.)

Of course it might be wise to drop those in a modes
section xorg.conf.d 
file and not actually try activating them with a
modes entry in the 
monitor section until the problem at hand is solved,
but it's definitely 
potentially useful information, for all three of the
reasons listed above.

Duncan, Felix,

I'm happy to get the modeline information, tho this
thread may be drifting some off the kde-linux audience.

With what I have from Felix now, I should be able to
make a functional display work on kde 4.6 or 4.7.

My plan now is to wait the the 12.1 DVD to arrive
before I experiment farther with a kde display. 

Last night I tried to install kde 4.6 from the
openSuse 11.4 DVD. I disabled all the repositories
except the DVD and stayed offline. 

Apparently some of the updating I did online in
between the DVD install and the kde 4.6 pattern
install changed some dependencies. Rather than risk
breaking what I have now, I'll wait for the 12.1 DVD
to arrive.

Felix, I have looked at your links now and I added
the 70- file to xorg.conf.d. Running lxde with file
in place didn't change anything positive or negative.

Let me post some results back to this trhread in a
week or two. Frank K
