The kernel log with the patch and kernel modesetting
With the patch the kernel modesetting works before starting X. The nouveaufb works too. After starting X, the screen is completely black, switching VT does not work. I need to ssh in and kill the X process. But that still does not bring back the VT. Created attachment 31429 [details]

It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report. In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one. Thanks, The Nouveau Team |

Created attachment 31421 [details] X logs and kernel logs with and without modeset=1 With modeset=1, the kernel segfaults, the X server segfault. With modeset=0, the kernel works fine, the X server does not complain, but the screen is black. I can switch VT and go to text mode. But X is always black.
