This looks like TMDSA load detection not working. Luc, can you look into this when you find the time?
You will find that, when you run rhd_conntest, the monitor only at certain times puts loads on the digital lines. We have seen the same problem with some other monitors...
This is a Dell 24" - pretty common I'd say.
So it is a problem with not the TMDSA load detection, but with the monitor attached to it, and a suitable strategy still needs to be proposed here.
Pardon my ignorance but how does the radeon-driver handle this?
radeon uses ddc to detect the presence of a monitor, and then (for DACs at least) falls back to load detection if ddc fails.

How do you distinguish between the DAC and TMDS parts on DVI connectors then? Also, hpd, with some quirks for the cards that, even though the hardware was there and is solid, didn't provide any HPD information through atombios (R5xx), tends to be rather solid. DDC has proven to be a gamble as well, as monitor manufacturers aren't as great as ATI is at making hardware. Luc Verhaegen.
