N.B. I have been unable to figure out whether or not any of the software involved is actually the newest available whatever. I'm happy to test newer software, compiling it myself if necessary -- but I will need you to tell me exactly what is out of date and where the newer version can be found, because the various webpages that purport to explain this all contradict each other :-( If there is one monitor connected to the HDMI port, and nothing connected to DVI or VGA, the computer boots successfully. errrr what? [ 12.163791] nouveau E[ PBUS][0000:01:00.0] MMIO read of 0x00000000 FAULT at 0x61d804 [ IBUS ] [ 26.237760] nouveau E[ PBUS][0000:01:00.0] MMIO read of 0x00000000 FAULT at 0x61a804 [ IBUS ] That'd be PDISPLAY.SOR[0x3].PWR and PDISPLAY.DAC[0x1].DPMS_CTRL for those following at home. No idea what we're (not) doing to make those mmio reads fail. As they're connected to "power", perhaps they're getting turned off for our convenience? Not sure. Perhaps it just doesn't have a SOR[3]/DAC[1]? Can you include your VBIOS, perhaps there's something interesting in there? From a successful boot, grab /sys/kernel/debug/dri/0/vbios.rom and upload it here.

Perhaps it *is* relevant, then, that when monitors are connected to VGA and DVI, both are activated (in mirrored mode) by the BIOS, but when monitors are connected to HDMI and DVI, *only* the HDMI-attached display is activated by the BIOS. > Perhaps it just doesn't have a SOR[3]/DAC[1]?

This computer is in my office, and I need to go home shortly, but I will be able to do further experiments tomorrow morning. Oh, one more thing: I do not have Windows on this computer at all, so I can't tell you what it does in the same configuration. Sorry. (I can probably dig up a Windows 7 install/recovery CD, though, if there's something useful I could do with it that doesn't involve repartitioning ;-) -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
