Hi, Stan. It really isn't so odd; after months (several weeks total
in transit) of messing around with the M3A78-T without success, I
decided to replace it; thus, the P5Q-EM. I long have used Asus
boards, but (after a failure of the USB circuitry on yet another Asus
board) I think that the P5Q-EM is going to be my last one.

Two different CRTs (iiyama and KDS XF-7G); two different LCD (NEC
1760NX). It seems to me unlikely that the same symptom is seen with
all of these, unless the motherboard is at fault. Of course, with the
P5Q-EM, the problem has to do with Xorg.

Again, the red and green lines with the M3A78-T are apparent even in
the POST displays.
Thankfully, with the P5Q-EM -- on which I just moments ago completed
the installation of Squeeze -- the installation of Squeeze solved the
problem! X is working!

Back to the M3A78-T: Inasmuch as I generally turn on the machine then
grab a cup of coffee while it boots, I seldom notice the POST; X is
running when I sit down to log in. And I seldom use terminal mode.
Consequently, I had been running the system for several months before
I noticed the red and green lines on the back background. The lines
are thin and somewhat faint, but once you notice them they are very
apparent.
