Ouch, anyone seen this before? I get this when I load ivtv-fb and then
restart X with a dual head config (using ivtvdev_drv.o). I have the
newest Nvidia drivers installed and am wondering if that's the issue. I
can provide the xorg.conf if needed. This is all running on FC2,
2.6.10-rc1, and I'm trying to get myth to spit out on my PVR-350
framebuffer. Anyone have any thoughts?
