Ralph Thomas Aussem: |Randall Hopper: |> 1) In fxtv when you can hear the audio, play with the appearance |> controls (Input->Appearance) and see if that changes anything. |If I change the appearance the display changes to. If I change tuner/video |the video signal changes. So the control functions seems to work. A few questions and things to try: 1) Which version of the driver are you using 2) By "the display changes too" do you mean that when you, for example, adjust the brightness up, you see the screen get brighter? 3) When you change tuner/video, what visual cues do you have that anything happened -- you said you see the video signal change? 4) As the screen gets brighter do you see solid white or do you see any background static in there? The fact that you see something change with the appearance controls confirms that the driver is dumping images into the driver memory buffer. 5) Sounds like either 1) the tuner isn't tuned right, 2) the video signal is somehow being disabled, or 3) there's a problem in fxtv with the color-space conversion code that crops up on your particular video card. If its one of the former two, whether you see static or not will help point that out. In case its the latter, try playing with the colorbar and pixel swapping options with direct video disabled (which you said is what its defaulting to). E.g.: fxtv -disableDirectV -colorbars -nobswap2Bpp Here's the full list of options to play with depending on your video mode: 15bpp/16bpp MODES: -nobswap2Bpp, -bswap2Bpp 24bpp (3Bpp) MODES: -nobswap3Bpp, -bswap3Bpp 24/32bpp(4Bpp) MODES: -nobswap4Bpp, -bswap4Bpp, -nowswap4Bpp, -wswap4Bpp, 6) If your card supports it, run in other color depths (8,15,16,24,32 bits per pixel) and see if you get the same result. 6) Finally, please mail me the output of: "fxtv -debug startup", and "xdpyinfo" and which video card you're using. Thanks, Randall
