Default Re: TV Not working with new nvidia drivers

Sorry Gorbayov, I figured you knew they were closed source..

Just to clear things up... I'm not affiliated with Nvidia. I was only able to speak with a developer once on these forums in another thread about this bug (there are 3 to my knowledge).

I'll link you to it here...

Same here with the 256.25 driver. The only difference here is with the new Xorg in Ubuntu Lucid, when enabling the "ConnectedMonitor" option, I completely lose signal to both the TV and my DFP.

Has anyone at Nvidia been able to reproduce this yet? As lanxton suggested, could someone look at the diffs between the working 185.18.14 driver and the versions after and see what has changed in the TV code?

Just to recap... This bug occurs for me in Windows 7 64-bit (anything later than 181.71 won't detect the TV) and Linux 32-bit (later than 185.18.14 won't work).

Default Re: TV Not working with new nvidia drivers

Possibly same problem here - no output to TV.

Card - WinFast 8400GS (256MB - G86 core)
OS - Ubuntu 10.04 64bit
Driver version: 256.29

I'm trying to configure 2 separate X screens (monitor + TV) - which worked like a charm in my old FX5200 + Ubuntu 9.10. Monitor works fine - resolution 1280x960, and I'm trying to get the TV-output to 800x600

Could someone explain these following oddities in my Xorg.0.log...

Code:
(II) Jun 16 01:11:56 NVIDIA(0): NVIDIA GPU GeForce 8400 GS (G86) at PCI:6:0:0 (GPU-0)
(--) Jun 16 01:11:56 NVIDIA(0): Memory: 524288 kBytes
512megs of GPU memory, and BIOS post messages and the box says that I have 256MB?

Code:
(--) Jun 16 01:11:56 NVIDIA(0): Connected display device(s) on GeForce 8400 GS at PCI:6:0:0:
(--) Jun 16 01:11:56 NVIDIA(0):     ViewSonic E95 (CRT-1)
(--) Jun 16 01:11:56 NVIDIA(0):     NVIDIA TV Encoder (TV-0)
So probably both display devices are recognized. Doesn't change if using the "ConnectedMonitor" -option or not.

Code:
(--) Jun 16 01:11:56 NVIDIA(1): TV encoder: NVIDIA
(II) Jun 16 01:11:56 NVIDIA(1): TV modes supported by this encoder:
*snip*
(II) Jun 16 01:11:56 NVIDIA(1):   800x600; Standards: NTSC-M, NTSC-J, PAL-M, PAL-BDGHI, PAL-N,
So PAL-B and 800x600 is supported. Then we validate the modes...

Code:
(II) Jun 16 01:11:56 NVIDIA(1):   Validating Mode "800x600":
(II) Jun 16 01:11:56 NVIDIA(1):     800 x 600 @ 50 Hz

(II) Jun 16 01:11:56 NVIDIA(1):     Mode is valid.
After that comes the tricky part:

(II) UnloadModule: "nvidia"
(II) UnloadModule: "wfb"
(II) UnloadModule: "fb"
Tried adding ModeValidation -options (see the commented line on my xorg.conf) - same thing happens. Unable to validate any modes even on auto-select.

And yes, GPU is not defective.

Does anybody else have this mode validation problem?

Mastus, your problem looks like it may be a different bug. After trying your mode validation options all my modes here are valid and don't give the errors that your seeing. The problem here is our TV encoders aren't even detected at all, while it looks like yours at least is.

Anyone have a solution to this yet? It has been years now...why can't the code be diffed at the point where the problem was introduced? It is obviously specific to a certain set of chip makers. What chips are we talking about?

Default Re: TV Not working with new nvidia drivers

THIS IS HOW TO FIX:

MAKE SURE THE T.V. IS ON and IN THE VIDEO MODE that is connected to the P.C.

RESTART THE COMPUTER...

Auto-detection works on startup, I tried and it worked... SIMPLE

VISTA 64 BIT here..
