From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Description of problem: Everything seems to go to plan with the installation, but it cannot detect the monitor. Setting it manually to Generic 1024x768 or Dell 1024x768 yielded no success. The Dell driver kinda worked, but the display was garbled on the right side of the screen. The Generic driver just plain didn't work. Leaving it as undetected would only allow 800x600 resolution, so I didn't even try leaving it alone. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Install FC3 from DVD 2. Complete GUI configuration wizard and the X portion will show the monitor as Unknown. Max resolution is 800x600. 3. Setting the monitor to the Dell Laptop Display 1024x768 will result (after logoff/logon) in garbled output on the right side of the display. Actual Results: The same results as stated. Expected Results: The crisp, clean GUI at a resolution of 1024x768. Additional info:
Misfiled against XFree86 (which does not exist in FC3), reassigning to "xorg-x11" component.

Could you clarify a bit what is meant by "Dell driver" and "Generic driver"? Does Dell supply additional video drivers, or are you refering to manually choosing your monitor from a list in our config tool? Please run "ddcprobe" and paste the results here. Also, please attach your X server config file and log file as individual uncompressed file attachments.

Sorry for the confusion! I was referring to selecting Dell manually as a manufacturer within your config tool. The results of the ddcprobe are below: ______________________________________________________ Videocard DDC probe results Description: ATI Technologies Inc. M3 Memory (MB): 8 Monitor DDC probe results Monitor DDC Probe failed. ______________________________________________________ I'm not clear on what file the 'log file' is referring to. Can you provide more information on what you need and I'll be happy to send it along. Thanks in advance!
Please upgrade to the latest rawhide xorg-x11 release, which contains numerous fixes that mays solve this issue. If the problem still exists in the latest rawhide xorg-x11 packages, it probably indicates a generic bug in X.Org that is not Fedora Core specific. In this case, file a bug report in X.Org bugzilla located at http://bugs.freedesktop.org in the "xorg" component, along with full details, and attach a copy of your X.Org server config file and log file. If you require technical support or assistance in obtaining this information, you can write to the xorg mailing list also. Once you've filed your bug report to X.Org, if you paste the new bug URL here, Red Hat will continue to track the issue in the centralized X.Org bug tracker, and will review any bug fixes that become available for consideration in future updates.

This indicates that your display either does not support DDC, or that you're using a KVM switch that does not pass the DDC signal through correctly. Since this is an M3 however, I'm assuming it is the former. A lot of older laptops with M3/M4 era hardware do not support DDC. As such, there's no way to autodetect the display, and it must be chosen from the list of available monitors manually. If there is no entry for a particular display, it can be set up manually by the user by hand editing the config file and punching in values from the monitor's manual or datasheet, or by submitting the manufacturer's .INF file for the monitor to us from Microsoft Windows driver download from their website. So, when our tool lists it as "unknown", this is correct and not possible to work around unless the hardware really does support DDC. >Setting the monitor to the Dell Laptop Display 1024x768 will result >(after logoff/logon) in garbled output on the right side of the display. This would be a video driver bug most likely, but a separate issue from wether or not DDC probing works (or is possible on this machine). > I'm not clear on what file the 'log file' is referring to.

The X server log file, X server config file, the output of lsmod, a copy of /var/log/messages, and any other information that might be useful. Also, please report the issue to X.Org as requested in comment #6 above, which will accelerate the likelyhood of finding a solution for this problem before FC4 is finalized. Either way, please respond as soon as you can, so we can make some progress on diagnosis for this.
