Displayport isn't supported yet.
Not a big deal, this was just a curiosity on my part. Any plans for support in the near future or does the lack of existing hardware make it a moot point right now?
Perhaps some useful information at http://fedoraproject.org/wiki/Features/RadeonDisplayPort Displayport already works on Intel hardware to some degree.
It's quite high on the TODO list of feature we want to support soon.
Created attachment 25334 [details] dmesg from 2.6.33 and dp connector Just tried again with the same hardware and the final 2.6.33 kernel. Stack from dmesg is gone but screen still blanks with 5 thin vertical lines across it.
Created attachment 25335 [details] dmesg from 2.6.33 and dvi connector For reference, same boot w/ dvi connector
