it's always good to get a 3rd perspective on things.

it can be explained by a whole host of non-error situations.  could be
the video timings aren't correct.  we don't know what version of X he's
running.  there might be a non-VESA timing in his config file.

i think this was already surmised.

to be honest, i don't understand what you're saying here.

what exactly do you mean by "monitor signal"?  communication between the
monitor and video card isn't synchronous in the sense that there aren't
"flow control signals".

see "man XF86Config-4".  look for the string "Ctrl+Alt+Backspace"

the X thing wasn't really explained either.  anyone can write a new init
file (and we don't even know if that would work).  the question is what
happened to the old file?

files don't disappear by themselves.  at least, they shouldn't.
