Flickering screen on a cinema display.

[Charles Plessy <charles-debian-nospam@plessy.org>]

Dear all,

I have just installed Etch on a powermac7,3 with a cinema display, but
very unfortunately, the screen flickers, making it difficult to work
with the computer.

I have found a hint on the fglrx page
(http://www.stanchina.net/~flavio/debian/fglrx-installer.html): it seems
necessary to reduce the refreshing frequency of the screen. However, in
/etc/X11/xorg, there are two ranges of, horizontal and vertical, so I
do not know how to tell xorg to refresh at 50 Hz.

Did anybody experience the same problem and found a solution ?

Have a nice day,
