Created attachment 361770 [details] Manual specification page for L767 monitor Description of problem: On a clean installation of Fedora Core 11, Xorg refuses to use the native screen resolution of my monitor which is 1280x1024 and uses 1024x768. My video card is "ATI Radeon X600 (RV370) 5B62 (PCIE)" (ChipID = 0x5b62) and my monitor is a Eizo L767. With and without a xorg.conf, it fails to do 1280x1024. I will attach my current xorg.conf to this bug along with the last Xorg.0.log file. Version-Release number of selected component (if applicable): X.Org X Server 1.6.3.901 (1.6.4 RC 1) Release Date: 2009-8-25 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.18-164.el5 i686 Current Operating System: Linux beast 2.6.30.5-43.fc11.i686.PAE #1 SMP Thu Aug 27 21:34:36 EDT 2009 i686 How reproducible: Always. Steps to Reproduce: 1. Start X 2. check resolution with xrandr -q 3. Actual results: Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096 VGA-0 disconnected (normal left inverted right x axis y axis) DVI-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 376mm x 301mm 1024x768 60.0* 800x600 60.3 640x480 60.0 720x400 70.1 0x0 0.0 Expected results: I expect 1280x1024 to be listed and selected on top. Additional info: From the log file it seems that DDC and the probed values disagree. I don't know much about this area but on Fedora Core 7 (which is what I just upgraded from, it used to work a charm with the DVI connection).
