My Apple Cinema Display 20" is not selectable from the list with
know LCD monitors. After selecting LCD Panel with the resolution of

1680x1050.

X being able to use the display at 1680x1050@60

Comment 2 Jurgen Kramer 2005-05-14 09:50:08 UTC 
With FC4t3 the monitor is still not properly detected during install but
is now selectable through system-config-display. After selecting "Apple Cinema
Display 20 LCD" and the setting the resolution of 1680x1050. I get a nice
1680x1050 screen with the proper frequencies! Good stuff.

system-config-display provides 2 extra resolutions namely 1600x1200 and
1920x1200 which are not appropriate for this LCD.

Thanks.

The monitor database is in "hwdata" package, not s-c-d.
Comment 4 Bill Nottingham 2005-05-24 17:05:27 UTC 
If it's in s-c-display, it's already in the monitor list.
