From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031114 Description of problem: When entering my Monitor type (AOC Spectrum 5Vlr) into the XFree86, XFree86 attempts to retrieve the modelines that the monitor is capable of using EDID. The monitor reports EDID of resolution 1024x768 and lower, while the monitor is capable of several resolutions higher than this (examples are 1400x1050 and 1280x1024.) It never used to be a problem to run 1280x1024 until a few days ago, after running a rather lengthy YUM Update session. Was the EDID support in XFree86 recently added to the Fedora Core 1? Version-Release number of selected component (if applicable): XFree86-4.3.0-55 How reproducible: Always Steps to Reproduce: 1. Install a AOC Spectrum 5Vlr monitor 2. Install a NVidia VideoCard (I am using a Geforce 2 MX 440) 3. Run XSestup 4. Try out X. Actual Results: Received a resolution of 1024x768. 1280x1024 was kicked out of the selection, because the monitor reported it unavailable using EDID messages. Expected Results: I expected to get the same resolution as normal, 1280x1024. Additional info: The following workaround exists for NVidia cards by changing your /etc/X11/XF86Config: Add your specific modes to the secion "Screen", SubSection "Display". Modes "1400x1050" "1280x1024" "1280x960" "1024x768" "800x600" "640xetc... When attempting to rerun X, you will likely receive an error message in your log file (/var/log/XFree86.0.log) saying something like: (WW) NVIDIA(0): Not using mode "1280x1024" (height 1280 is larger than (WW) NVIDIA(0): EDID-specified maximum 1024) that these modes are not supported compared to EDID messages received from your monitor and they are effectively unavailable. Than add the following to Section "Device" where your NVidia card is defined: Option "IgnoreEDID" "true" Option "UseEdidFreqs" "false" This will make the videocard/XFree86 ignore the messages received from your monitor. Most likely you will have to finetune the modelines using the "xvidtune" program and add modeline information to Section "Monitor". For example: ModeLine "1400x1050" 122.00 1400 1480 1632 1888 1050 1056 1068 1090 +hsync +vsync I am surprised that the monitor is reporting resolutions lower than it is capable off. Is this common in monitors nowadays?
