Hi Anne and everyone,

I am getting the same error message with xawtv:

  WARNING: couldn't find framebuffer base address, try manual
         configuration ("v4l-conf -a <addr>")

Following the instructions above, I searched Xorg.0.log but I don't
find anything which looks useful. The only line which includes
"framebuffer" is this one:

(**) NVIDIA(0): Depth 24, (--) framebuffer bpp 32

I've have a Hauppauge PVR-150 card and I am running FC6 with kernel
2.6.18-1.2849. My video card is a nVidia GeForce4 with the nvidia
driver packages loaded:

$ rpm -qa | grep -i nvidia
xorg-x11-drv-nvidia-1.0.9629-1.lvn6
kmod-nvidia-1.0.9629-1.2.6.18_1.2849.fc6

Anyone have any other ideas on how to determine the framebuffer
address? I really hope to get xawtv working. (tvtime alas doesn't
support PVR cards AFAICT; mplayer is a bit too arcane.)

Thanks.
