Hi, currently DDCReg in radeonfb is hardcoded to CRT port (secondary port, primary DAC). I've working code to detect connector type. On my board it finds the CRT port and DVI port. The latter is ignored because dviDisp_type is MT_NONE. If crtDisp_type is MT_NONE then it will use the DVI port. What should I do if both port are in use? Read EDID from primary port and ignore secondary? Luca -- Reply-To: kr...@kr... Home: http://kronoz.cjb.net Software is like sex; it's better when it's free. Linus Torvalds |

Does ATI have a standard default here? When you boot using the ATI VBIOS and no framebuffer driver, which port gets activated when a monitor is attached to both CRT and DVI? Also, aren't there four ports total? CRT DVI TV Out DFP I haven't noticed this because I am using the CRT connector of my panel. I've lost my DVI cable. --- Kronos <kr...@kr...> wrote: > Hi, > currently DDCReg in radeonfb is hardcoded to CRT port (secondary port, > primary DAC). > > I've working code to detect connector type.

In the meantime, I'm working on dual head support, though I'm not sure I'll have that finished soon. Ben. |

If both port are in use DVI is considered primary and VGA secondary. Luca -- Reply-To: kr...@kr...
