** Summary changed:

+ Primary display unusable with dualhead nvidia card and nv driver
** Description changed:
Binary package hint: xserver-xorg-video-nv
Ubuntu 8.10 Intrepid Ibex
- xserver-xorg-video-nv v1:2.1.10-lubuntu2
+ xserver-xorg-video-nv v1:2.1.10-1ubuntu2
Nvidia FX5600, Dell D1226H monitor, Sony XBR800 TV
With both a fresh install and the Live CD, when I have both my VGA CRT
monitor and my DVI CRT TV connected, the monitor display is just a mess
of colour, as shown in the attached photo. Also, switching to a
terminal window, once the screen is full, it stops refreshing or
displaying any output and I have to switch to another terminal window
and back again to see the response to each command I enter.
With the install, I can obtain a desktop by using the vga= switch, but
there is no mouse pointer, which makes it impossible to use and it still
had the terminal window problem as described above. With the LiveCD, if
I boot into Safe mode it works using VESA, but only at 640x480 which is
too small to be able to access some of the buttons on windows.
After reading Bug #43710 I tracked the problem down to my TV being
connected on the secondary DVI port. Strangely, unplugging the TV power
from the wall didn't help, so I guess it must hold a residual charge
that still enables the PC to detect it. Disconnecting the DVI lead fixed
it.
It seems that when both my TV and monitor are connected, what happens is
that xorg uses the TV as the main display (which displays correctly) but
it's trying to clone it on the monitor, which leads to the problems
mentioned.
I'll upload a few log and conf files in additional posts.
