Xorg.0.log, while running 3.9.0-rc6
I've tried the direct approach here of staring at the commit. 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. Please try out https://bugs.freedesktop.org/attachment.cgi?id=84758 This helped another NV1A user. This should be fixed in nouveau/master. If the problem remains, feel free to reopen. I'm experiencing the same problem on a debian kernel 3.11-0.bpo.2-486.

The strange is that the monitor is connected to a VGA, not DVI (no DVI is present at all) Tell me if I can help someway Thank you Claudio Well, my fix only went into v3.13-rc1, so your 3.11 kernel almost certainly doesn't have the fix. Please try the latest rc kernel and see if your issue still appears there. Do note that not all is well with NV1A after this fix -- there is still another NV1A bug open about resume issues. Thank you very much for your answer. I'm a bit in troubles with upgrading to 3.13, at the moment. But I manually applied your patch to current debian 3.11 source and it works perfectly for me Claudio |
