Found it!
This card is using uniphyB which wasn't detected correctly. The BIOS helped to locate the problem.
Great work, Egbert!
Just for the record: What is uniphyB? Could this be the source of some of the other (few) connection table breakages we saw lately?
uniphyB is one of the transmitters introduced with DCE3.0. It is capable of doing TMDS (DVI + HDMI), DP. If you see the breakages on RV620 or RV635 then it could well be this problem. Most of the few breakages I'm aware of were on R5xx, though. The objects tables on r6xx and up are a lot more reliable than the supported device lists on r5xx.

I registered on this list yesterday to try and solve this very problem with the Sapphire HD3450. I took it upon myself to create a quirk for this card in rhd_id.c. I found that UNIPHYB was the output that was supposed to be used for DVI on connector 1. When I set it up to use UNIPHYB X would start up, but I'd get no output (monitor indicated lost signal). This is the quirk I added:
#define DVI_HD3450 \ { { RHD_CONNECTOR_TV, "7PIN_DIN TV1 CV", RHD_DDC_1, RHD_HPD_NONE, \ { RHD_OUTPUT_DACB, RHD_OUTPUT_NONE }}, \ { RHD_CONNECTOR_DVI, "DUAL_LINK_DVI_I CRT1 DFP1", RHD_DDC_0, RHD_HPD_1, \ { RHD_OUTPUT_UNIPHYB, RHD_OUTPUT_DACA }}, \ { RHD_CONNECTOR_DVI, "DUAL_LINK_DVI_I CRT2 DFP2", RHD_DDC_1, RHD_HPD_0, \ { RHD_OUTPUT_KLDSKP_LVTMA, RHD_OUTPUT_DACB }}}
and for the device:
{ 0x95C5, 0x174B, 0xE670, "Sapphire HD 3450", RHD_CARD_FLAG_NONE, DVI_HD3450 },
I experimented a bit by using UNIPHYA instead of UNIPHYB and then I'd actually get video in X, but it looked really strange and distorted. Would you expect that a quirk like the one above would fix this? Thanks, Brad -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
