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.

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).

/var/log/Xorg.0.log (preferably with the line `Option "ModeDebug" "On"' in the
xorg.conf device section) would be informative here.  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.

And this is my xorg.conf file.

--- Comment #6 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
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
