Actually, it gets the EDID from the VGA panel just fine, also shows me
the modes it supports. DVI1 has no edit, though it gets its allowable
modes from the dvo_ds2501 module.
I now tried to relocate VGA1 to crtc 1, with Daniel's patch. Results are
even weirder. I can *set* the resolution to 1280x1024 on VGA1, just that
it does not deliver this resolution. My monitor claims (and my vision
confirms) that this is still the same 1024x768 mode as on the internal
panel.
I can again turn VGA off, relocate it to crtc 1, turn it on again, still
says its a clone of DVI1 even though it's on a different crtc.
Chipset (lspci) says its a 82830M/MG graphics controller, PCI id
8086:3577. This *should* be a true 830MG (specs agree), thus I *believe*
it should have two display pipes. The R31 is built around the very same
chipset and has no problems with independent output. Looks like they
shared the VGA and DVI output,and left the other output just dangling.
Weird.
