My first KnoppMyth setup:
- no pvr card
- nvidia gforge 440 mx + tv-out working

After a few weeks I put the machine into the living room again and added a PVR-350. It worked almost instantly (except for NTSC - PAL issues).
The only thing was that the live-tv image seemed to drift up-and-down one pixel. So I had to change something......

I edited the XF86Config-4 and changed the frequency and added a modeline for PAL. This gave very strange results (ending in a signal 11 and a screen with black vertical lines. Okay, lets copy the backup.


Soooo .... because the install the first time was very straightforward, I tried to copy the nvidia-tvout sample and change it, but this gave much the same problems (I can see the nvidia splash screen before X locks).

From the log, it seems like the driver is setting this mode:
(**) NVIDIA(0): Mode "800x600": 40.1 MHz, 38.0 kHz, 60.5 Hz

When I change the driver from nvidia back to nv, I get the mythv
screen, but with the wrong frequencies. With the nvidia driver X locks up again (signal 11, vertical lines in X).

I did install-update for the latest nvidia drivers, but that didn't solve anything.

Where do I start?

TIA

I would first find out what refresh rates you need. I know the sample file is for NTSC and that is 60Hz vert I also believe I heard that PAL is 50Hz vert, but I'm not sure if the X config and modelines need to be adjusted to reflect this, seems like I read somewhere that you still use 60, but I'm not sure, so the first thing I would do if I were you is put google to use and find out what your modelines and refresh rates are supposed to be for PAL. I can't really help you there I have no access to a PAL TV or PAL signal.

The last time I got it working I only rememer having changed TVStandard and TVOutFormat to get it working.

I remember having checked the 60 Hz but it doesn't need to be changed. I guess that's the tv-out magic from the nvidia card? So I guess it's not a modeline issue?

Hi,

I have been playing with the TVOUT for NVidia for some time now and this is my experience.

1. Download the very latest NVidia drivers 6111.
2. Use a XFree86 Modeline generator e.g http://xtiming.sourceforge.net/cgi-bin/xtiming.pl.
3. I set the box to run 720x576 (PAL).
4. Manually set the vertical refresh rate to 50 or 60 (both worked for me but 60 was more stable).
5. To correct any instability in the on screen display open a terminal window and run nvidia-settings and adjust the screen flicker setting to suit your TV.
6. Make sure you have set the correct options for TVOUT in XFree86 (see the nvidia readme). I will send my config if required.
7. Watch out for errors e.g. virtual size too small blah blah blah. If this happens set the XFree86 config to include virtual 720x576.

NOTE: If you have any problems running 720x576 then set to either 640x480 or 800x600 and remove any mode lines the Nvidia driver will automatically detect supported settings.

Thats it for now, I hope this helps.

Tim.

I've installed the latest driver.

The modeline for 720x576@60 with the nv driver gives an image that seems to have PAL/NTSC problems. With the nvidia driver I see 3 or 4 times the logo and then only vertical lines, it even messes my logon screen (after ctrl-alt-f1). Is there a mode reset command for the console? ( I'll do some more reading on linux).

The last part of the log:


Any help appreciated.

Michael

BTW: the unresolved messages where gone after removing the "dri" module as stated in the readme from nvidia. The problem remains the same.

I had similar problems when installing the driver, I found that disabling GLX in the XF86Config-4 solved the server fault.

Simple comment out GLX support.

Hope this works.

Here is my config, I have reverted back to running 800x600 because of TV not showing fullscreen correct. You should be able to work it out from this.

I commented out the load "glx" and everything works fine again.
Many, many thnx.

Michael

You can fix the load glx problem easily enough, go to the 3rd page of this thread and look for the message by me on Aug 1:
http://mysettopbox.tv/phpBB2/viewtopic.php?t=1871

The fix solves the glx problem, thanx. On to the next

Switching from X to the console doesn't restore the console properly. The readme states I should move to a newer version of xfree86, but I am allready running 4.3.0 as mentioned in the nvidia readme.
