The latest xorg-x11-drv-* driver packages contain videoaliases files for kudzu et al. to use for video card autodetection and driver mapping.
One further clarification I should make, is that this request was for "video card" detection. Monitor/display detection is a separate issue, which is done by the ddcprobe utility, which gets invoked by system-config-display, and is x86 only. The X server can also do monitor detection, however our default configurations specify the monitor in the config file in most cases. The X server still probes the display when it is possible to do so, but that information is not always used. Video driver DDC problems, generally should be reported directly to X.Org bugzilla to ensure the maintainers of the particular driver see the issue. In some cases it is a driver bug, in other cases a hardware limitation, or a software limitation that can't easily be overcome. KVM switches can also block the DDC signal. Another problem which someone has brought up, is that on DFP and LCD displays, and in particular wide-screen panels, often the resolution that gets configured by default, does not match the physical resolution of the DFP/LCD panel, causing hardware scaling to be used, resulting in an ugly display. For laptops and systems with Intel hardware, this is a video BIOS limitation which can not be worked around currently without documentation from Intel. I believe that some "via" video hardware has a similar problem. In all cases of this nature, my recommendation is to try and narrow down the problem you're having /before/ reporting a bug anywhere. A good place to get helpful troubleshooting info, is xorg@xxxxxxxxxxxxxxxxxxxxx and #xorg IRC channel on freenode. In some cases, these limitations can be worked around with ugly hacks that are out there (ie: i810resolution hack), and in other cases modelines need to be added to the xorg.conf. Of course there may be a real bug somewhere, but it'll be more evident once you've done some direct investigation based off advice from the xorg mailing list. Only then should one report a bug, and it should be filed in the X.Org bugzilla at: http://bugs.freedesktop.org Hope this helps. I'm getting good feedback from people, so I'll try and post more advice here if more examples pop up. If someone feels like summarizing any of this on the Fedora wiki, or paraphrasing, etc., feel free. Thanks everyone for testing, and providing bug reports and other forms of feedback! -- Mike A.
