Sorry. I did say to Alan that I would look at that, but haven't. Our Permedia card is now on a Windows machine, so I can't easily do anything about this any more. I did find that DDC worked with a monitor connected to the VGA port, but not to the digital connection. I have some non X tools which could get DDC information via the digital connection, so XFree86 is definitely deficient. It is some months since I looked at this, but if I remember correctly one of the tools that I tried used the same VBE/Int10 calls as XFree86 and also failed, while another used different ones which worked. These tools are ddcprobe and ddcxinfo, which are or were part of RedHat 6.2 anaconda. I had endian or bitfield problems with the modelines when using these tools, so do check the results if you use them. -- Dr. Andrew C.
