It all seems generally plausible, but as you probably noticed, it's quite rather large. I think that the way to go for solving this will be to run an mmiotrace of it working and then not working, and compare. Once we know exactly which functions aren't being called, it should be easier to figure out why. Would you be up for putting the two mmiotraces together? Here's a guide on how to do it: https://wiki.ubuntu.com/X/MMIOTracing (but replace "nvidia" with "nouveau"). You'll obviously need to compile nouveau as a module. BTW, I assume that the monitor goes blank as soon as the modesetting happens, not when X starts? It does seem to find your monitor, X gets EDID (which another NV1A user isn't getting, odd). But it just never turns the crtc on... or something. Also, could you provide some details about the physical hookup -- is this DVI-D (digital) or VGA/DVI-A (analog)? Is there just a single connector or are there multiple ones? What type(s) of connector? Lastly, might be worthwhile to just try the latest and greatest kernel (3.11-rc6). I have pretty low hopes for a fix to nv1a going in since 3.9, but who knows, something could have jiggered it. -- You are receiving this mail because: You are the assignee for the bug.
