[SATLUG] nvidia tv-out problem

[Mark D. McCoy]

Hey all, anyone using an nvidia card for tv-out?

I'm finally getting my mythtv box up and running, had issues with the
via m10000 board (saving that for a carputer, now), so I'm using an
extra AMD Duron 1.3G machine I had lying around. I have an Nvidia
geforce 4 card w/ tv-out on it, and I'm trying to get the tv-out part
working.

BTW, this is on a gentoo system with the binary nvidia X driver.

The console starts up on the TV great, at 800x600 (at 1024x768 the fonts
are too small if I had to admin this using the TV). Boot splash comes
up great, and framebuffer console shows the login prompt. OK.

Now, X is the problem. If I use a "default" xorg.conf (generated with X
-configure), the X server starts at 640x480 on the TV. The X server is
up, but it only displays a black screen with the mouse cursor on it.
The Xorg.0.log shows everything working OK. Using 'xhost +localhost' I
can run programs on the X server, but they don't show up. Still a black
screen. The mouse changes as it goes over elements on the screen (over
an xterm it changes to a bar, etc), so the programs are connected to the
X server.

If I add the monitor refresh rate (from nvidia's readme), the display
comes up at 1024x768 with the nvidia logo. The logo stays around with
the mouse cursor on it, and the mouse cursor has the same behavior as
before. If I set "NoNvLogo" "True" then the background is black, as before.

This is really frustrating, since it seems to be _almost_ working!

You might want to take a look at yanc (yet another nvidia configurator)

I've used it before to configure the more complex nvidia features. Back
up your config files, it's going to edit them.

Got it working with newer nvidia drivers. Looks awesome!

Of course, now the sound is giving me fits! :-(

The alsa driver for my motherboard (snd-via82xx) loads, creates the
devices, etc.. I get no sound out of the TV. Yes, I unmuted the
channels in alsamixer and did an 'alsactl store'. Myth is able to
adjust the PCM channel just fine, but no dice from the TV. I will plug
a pair of headphones in and see what's up...
