This should get picked up by the nv_load_detect function in nv_output.c (assuming the monitor is connected via the vga connector and not some composite video input thing from the tv-output). It might therefore be worth you instrumenting the function to make sure it's being called and also what your card's comparison testval is set to by the bios tables (pNv->VBIOS.dactestval). Assuming there's nothing obviously wrong, xorg logs from the nv driver and if possible the proprietary nvidia driver (using -logverbose 9 as an argument to the Xorg binary) will help show if their load detect functions can pick it up. Confirming with quite new Samsung 226BW 22" panel. This monitor doesn't send correct EDID (requires drivers under Windows, doesn't detect modes automatically from nvidia blob or even Windows), and with Nouveau ignoring modeline settings I am able to use only 1024x768 mode (monitor's native mode is 1680x1050).

Also, I'm fairly sure it is possible to force a mode (assuming the monitor is detected as connected, which it is in your case) in the xorg.conf, so attach that as well and indicate what you've tried setting in it.

Xorg.0.log
This is my Xorg.0.log. I am using the same xorg.conf that worked fine with nvidia blob. Notice that the log file doesn't even mention 1680x1050 modeline.
In case it's case sensitive, I've tried to set the option like
ModeLine
Modeline
modeline
But didn't help.

xorg.conf
And this is my xorg.conf file.
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 18761 [details] log from X -config xorg.conf.new with old CRT attached (the same without any monitor) AMD64 system with NV44 PCIe. (ASUS GeForce 6200LE) xf86-video-nouveau as of a few days concludes "No valid modes." if I run X -configure with no monitor connected, and when my old CRT monitor without EDID is connected.
