Xorg doesn't start after boot. Internal display connected to LVDS fails, but external display with D-Sub works. Tested on Fedora 12 LiveCD with nouveau.modeset=1. Hardware: http://www.smolts.org/client/show/pub_63cc826b-b57b-401b-ad0c-a27b0cb5b5d3

Does the display work with nouveau.modeset=0? And, what resolution does your panel have?
No it doesn't. Resolution is 1024x768.
The info in the VBIOS about your panel is confusing for nouveau, we end up with *no* valid method for detecting your panel's mode. Your VBIOS has a 1024x768 mode listed for your panel, and nouveau detects that it should use it if it's using those mode tables. However, another VBIOS table tells nouveau to *not* use those mode tables. I'll attach panel-strap-mode.diff to force the use of the tables. Now, the entry for your panel gives a valid index into the DDC table so it's possible it reports an EDID that we should use. I suspect this is probably the case here, and we make a bad decision on when to use DDC on your card. I'll attach panel-ddc-mode.diff for this. Can you try each patch separately and report which (if any) work for you. Thanks!

Any update? This should be fixed in latest git too..
(In reply to comment #8) > Any update? This should be fixed in latest git too.. I have a similar, if not the same problem. Your second patch already seems to be in git, and I also tried applying your first patch, but nothing changes. I have tried with both modeset=0 and modeset=1, Xorg.0.log and dmesg attached respectively.

This report seems to be against a very old version of nouveau. Is this still an issue with recent nouveau? If we get no status update within one month I will close this bug as unreproducible.
Closing as we got no new info from reporter and the bug is against ancient version of nouveau.
