Bug#593784: xserver-xorg-video-nouveau: fails to detect monitor resolution

| Well, so far we have not found a solution. :-(

| You definitely need a Monitor section in your xorg.conf,

My situation has become worse.  After leaving the machine
for more than four months because I stayed abroad, I came
back and dist-upgraded it (without thinking much).  Then,
I lost the nv driver!  It's no longer available in the Debian
testing repository.

That means, I'm left with nouveau, which cannot use the correct
resolution of my monitor.  The correct resolution is 1280x1024
but nouveau chooses 1024x768.

So, I tried to tell it to use the correct resolution.  I copied
the previous /etc/X11/xorg.conf which worked with nv and modified
it to the contents quoted below.  I have just deleted the "Files"
section, which had been empty, the "InputDevice" section, and the
"ServerLayout" section, and I've just replaced "nv" with "nouveau".

The machine boots up correctly, except for the screen resolution.

I'm desperate.  What other drivers work with nVidia cards?

Regards,
Ryo
