Does that apply to _all_ radeon cards, for example also to my FireMV
2400 (that has two M9 chips) ? With two CRT's it does work, and the
card only has 4 DVI-I outputs. Currently I don't have any DVI monitors
to test though :-/ With the "Auto, Auto" setting I do get the CRT's to
work, the output in Xorg.0.log is than as follows, which does say
something about an external TMDS;
(II) RADEON(0): Reversed DAC decteced
(II) RADEON(0): Primary:
Monitor -- CRT
Connector -- DVI-I
DAC Type -- Primary
TMDS Type -- Internal
DDC Type -- DVI_DDC
(II) RADEON(0): Secondary:
Monitor -- CRT
Connector -- DVI-I
DAC Type -- TVDAC/ExtDAC
TMDS Type -- External
DDC Type -- CRT2_DDC
