greets!
I was trying to get a second monitor (a tv) to work using xrandr. I
noticed that the screen on the laptop would suffer severe, almost
'psychedelic', effects if I hit a certain setting.
unfortunately I don't recall the setting but the ill effect was
consistent and rendered the disply nearly unreadable. and the only
solution was to end the session.
then by accident I hit the 'save this configuration' key and now the
setting is permanent.
btw I created a second user and it doesn't suffer from the problem.
I cannot find a way to restore the proper display setting.
My guess is that you did something awkward to the color profile or
gamma correction. No idea where that information is stored, though--I'd
probably resort to grepping through likely directories looking for
"[Cc]olor". If it affects only a specific user, then the setting is probably
in your home directory, since most distros don't like mingling user settings
with general system settings.

As David Wright and Dan Ritter have said, I was on a false track
with seeking configuration files for xrandr. (I assume - haven't
checked - tderandrtray is some kind of front-end for xrandr though.)
As it turns out, I'd tried yesterday to make sense of things via
xgamma and the gamma utility in tderandrtray (aka xrandr?), to no
avail, that is, I can improve aspects of the display but not restore
it.
I'm on the hunt now for where color profiles are stored, the hunt will
be undertaken tomorrow unless I decide to just stick with the new user
setup. (incidentally it has fixed some font size issues I had.)
