Description of problem:
My Apple Cinema Display 20" is not selectable from the list with
know LCD monitors. After selecting LCD Panel with the resolution of
1680x1050 I only get a resolution of 1440x1050 because there is no mode line for 
1680x1050.

Version-Release number of selected component (if applicable):
-

How reproducible:
Allways

Steps to Reproduce:
1. Run system-config-display
2.
3.
  
Actual results:


Expected results:
Able to select the Apple display out of the list with know monitors and
X being able to use the display at 1680x1050@60

Additional info:
Tested with Nvidia 6600GT (PCI-E) card using the default nv driver.

From Xorg.0.log:

Manufacturer: APP  Model: 921d  

Modeline needed to get 1680x1050@60 working:
Modeline "1680x1050" 149.05 1680 1800 1968 2224 1050 1051 1054 1117 # 149.05

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.
