What happens if you run 'ddcprobe' on the installed system?
Comment 2 Jurgen Kramer 2005-05-17 12:55:56 EDT
Running ddcprobe gives:

[root@paragon ~]# ddcprobe

Monitor DDC probe results
Monitor DDC Probe failed.
[root@paragon ~]#

This is with a PCI Express 6600GT
Comment 3 Jeremy Katz 2005-05-18 21:07:45 EDT
Unfortunately, this means that the monitor isn't probe-able via the generic
probing mechanisms and can only be probed via card-specific i2c routines that X
doesn't export :(
