Anyone have any other ideas on how to determine the framebuffer address?
After more searching, I found this: [...] Re: nvidia-8756: xawtv broken Finding the base address was part of my extremely-hackish workaround for this bug (I hardcoded the base address into the X V4L driver). This is obviously a REALLY BAD idea, but it does work. Basically, you figure out which PCI bus:slot.function your device is, then look in your /sys/bus/pci/devices/0000:<that bus:slot.function>/resource file. That will list all memory ranges that your video card has reserved. One of them should have a size that corresponds to your amount of video RAM; use the first field on this line. (The first field is the start address, the second field is the end address, and the last field is a set of flags.) [...] http://www.nvnews.net/vbulletin/showthread.php?p=1008836 In my case, it would be this file: /sys/bus/pci/devices/0000\:02\:0a.0/video4linux\:video1/device/resource and I am guessing this value: 0x00000000f0000000 running $ v4l-conf -a 0x00000000f0000000 works, but still a black screen. :( Any other ideas? -- Colin Brace Amsterdam
