[SOLVED] nvidia tv-out broken

karag · 2007-08-29 18:47:41

Hi all -
I've been using my laptop monitor connected to the TV for a long time, to watch films etc, with the config below. I have a nvidia geforce 7300 go in a Dell inspiron 6400 laptop. This has worked well but now suddenly all I get is black on the TV screen. When X starts and exits the screen flickers - which suggest that at least the s-video connection is ok. The error in Xorg.log is

NVIDIA(1): Unable to find available Display Devices for screen 1.

I tried reverting to old drivers but no difference. Can someone please help me to get the tv out working again?
Thanks!

here is xorg.conf

I'd setup a xorg.conf which runs with only the laptop's monitor and call nvidia-settings from within X. This configures dual head setups pretty well.

I always do that, save the new xorg.conf to my home directory and modify the system's xorg.conf where it's needed.

I tried this but nvidia-settings just does not see the TV at all. If I click 'detect displays' the TV flickers but it will not detect.
If the TV is flickering when X starts, is this reliable indication that connection between laptop and TV is working? If so, perhaps this is just a driver/configuration problem.....

well after messing about with twinview and millions of obscure nvidia driver options, it works again.
The important changes I made regard the use of options "ConnectedMonitor" and "UseDisplayDevice".
Specifically, I added

Option        "ConnectedMonitor"   "DFP,TV"
Option        "UseDisplayDevice"    "DFP,TV"

to each device section of the xorg.conf posted earlier.
Probably I don't need both but hey it works.:D
