Comparing your scripts with what I'd actually put into xorg.conf, there were
some extra modelins from knoppix, but the only real difference was that I'd
put the dri section in. I thought it unlikely that this affect it, but I've
taken it out anyway. It still is blinking.
One last thought. I did install a wireless mouse and keyboard at the same
time as the dvi cable. I have a feeling that the blinking tends to happen
when I move the cursor with the mouse. Is it possible that there is
interference from the mouse?
