Description of problem: During install ( GUI mode, from local CD ), my monitor model is not detected. In the Monitor selection screen "Unprobed Monitor" is selected. My monitor type is Hyundai HT-7695B. It was correctly detected on my older gfx card ( SiS 6236 ). My current gfx card is Hercules 3D Prophet FDX 8500LE ( Radeon 8500LE). The older gfx card is still inserted but not used ( it is PCI, the radeon is AGP ). If I run ddcprobe on VT2 during install, I get : Videocard DDC probe results Description: ATI Technologies Inc. R200 Memory (MB): 64 Monitor DDC probe results ID: @A@9ba9 Width (mm): 120 Height(mm): 320 Version : Fedora Core Test 3

The monitor is giving back bogus DDC data, so we throw it out.
What do you mean ? It worked "perfectly" on another gfx card. Does my radeon card mangle the DDC data ? I am confused ...
Same hardware, new SW ( FC2 ) , same problem, but X can detect the DDC data without problems.

X uses card specific i2c bits instead of the generic real-mode LRMI interface. And without X exporting a way to get at that (since having that code multiple places would be bad, especially as it changes with every bloody card), there's no way to do that and we have to use the generic method that depends on BIOSes and other such things to not suck :)
