Marko:
Thanks for the multiple confirms of questions, I'll give it a try now
that I know what I was going to do isn't horribly wrong.

I tried out a couple of combinations and know that
1) the xrandr command does work
2) switching video to DVI-I-0 shows the same "kvm lack-of-focus" problem
which xrandr fixed
3) after scanning web and etc/rc.d files, it seemed to me that I should
have been able to put this xrandr command in rc.local and have it occur
when the boot is finished --- did not work (but, since I have to have
the kvm pointed elsewhere to test, not certain if my test is valid)
It would seem to me that there should be a way I can have the boot
process look to the info from xrandr and set itself to the "+" setting,
but I can't figure out a way. I know its been an issue for many Fedoras
/ RHELs which ctrl+alt+backspace at the gui login splash would solve,
but f12 seems to only let me get that feature back once I have logged in
(and kicking the display and getting an X restart once logged in isn't
as clean as the xrandr command once logged in).
Thanks for help,
Paul
