Description Jay Fenlason 2006-11-29 22:29:27 UTC

Description of problem: 
I hand-edited the xorg.conf generated by system-config-display (see bz#217788) 
and replaced the Modes line for Screen1 with a copy of the one from Screen0: 
'Modes    "1600x1200" "1600x1024" "1440x900" "1400x1050" "1280x1024" 
"1280x960" "1280x800" "1152x864" "1152x768" "1024x768" "800x600" "640x480"' 
and started the X server.  The right head came up at 1600x1200, but the left 
head is doing only 800x600. 
 
The display card in question is: 
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY 
[Radeon 7000/VE] 
 
Version-Release number of selected component (if applicable): 
xorg-x11-server-Xorg-1.1.1-48.2.el5 
 
How reproducible: 
Always 
 
Steps to Reproduce: 
1.Start X 
2.Look at the two heads 
3.run xdpyinfo 
   
Actual results: 
800x600 on left, 1600x1200 on right 
 
Expected results: 
1600x1200 on both 
 
Additional info: 
This worked semi-fine on RHEL3, although X would do unpleasant things like 
segfault if I used the wrong cables or had the input selector switches on the 
monitors in the wrong positions.
