From the rate of flicker I'm pretty sure the vertical refresh rate is
about 60 hz. If I could figure out how/where I would just plug in the
correct figure. O read that bit in x.org but still don't have a clue.

The file can be edited in Kate as root much easier than Vi.

Mmmm... before you go off hacking xorg.conf maybe you should try:
sudo dpkg-reconfigure xserver-xorg
at the commandline. I have been following the thread and I'm pretty
sure (I hope) no one has suggested this yet.

No, no one had suggested that approach. It worked fantastically to
reconfigure the keyboard but that's all it did. It was well worth a try.
Thanks anyway.

Did you try xvidtune? It's great if you want to see what settings your monitor
is running at or if you want to tweak the settings and add a modeline to your
xorg.conf.
Run it and you don't have to to be "pretty sure" what your Vertical or
Horizontal
Sync is, you will have it for a fact.

What a neat little toy.

Well,......................I guess I'm sort of like an old hound dog
with a bad nose. Barking up the wrong tree. Sorry to have caused so much
commotion.

With all the thrashing and trashing I totally trashed the install. No
big deal at this point cause it was fresh and nothing of any importance
loaded into it yet.

Re-installed and ran xvidtune. It looks like everything is in spec.

Now I don't know what to do to fix the flickering screen.
