I upgraded my old laptop from edgy to feisty yesterday, I only use this
laptop to view videos on my TV and the upgrade broke this completely, I
cannot get my TV-out to work anymore using the nvidia glx drivers.

the graphics hardware is the GeForce4 420 Go

the relevant sections of my xorg.conf:

Some errors in my /var/log/Xorg.0.log:
(--) NVIDIA(1): Connected display device(s) on GeForce4 420 Go at PCI:1:0:0:
(--) NVIDIA(1):     Nvidia Default Flat Panel (DFP-0)

I guess I will have to try an older version of the nvidia driver to see
if that fixes it...
