Probably not old enough, I'm afraid. Then again, I bet I have one from
when I used to run Mandrake... I backed that stuff up on CD a long time
ago... Now that I think about it, I'm positive this was in XFree86 3
days.
Is it related to my horiz sync and veritcal refresh numbers ?? They're
taken from the manual for the monitor. I have to assume they're correct.
FWIW, the numbers are:
HorizSync 31-92
VertRefresh 50-150
When I configured X, debconf mentioned that VertRefresh settings above
160 were rare. Is 150 "too close" ?? What would it do if I lowered that
number ?? Make things look bad ??
