Console on framebuffer ivtv tvout

I haven’t got this working at all yet. What I’m trying to achieve is the linux kernel console using ivtv framebuffer and tvout so I can CTRL-F1 and see the console on my TV and also keep an eye on the console while booting my mythtv.

I followed this guide: http://www.savvyadmin.com/console-framebuffer-in-ubuntu/ and used this table of grub vga options: http://techpatterns.com/forums/about342.html

No luck so far.

Using udev to make sure my webcam always has the same device name

On ubuntu, I added a new file /etc/udev/rules.d/50-webcam.rules


SUBSYSTEM=="video4linux" ATTR{name}=="OV511 USB Camera" SYMLINK+="ov511_webcam"

 

As you would find after reading this helpful udev guide the above rule causes udev to match any devices in the video4linux subsystem that have a name attribute set to “OV511 USB Camera” and create a symlink /dev/ov511_webcam pointing to the real device whatever that might be. I could have also forced it to name the device /dev/video1 using the NAME= command instead of SYMLINK.

Thanks to Florian Kulzer and Nigel Henry on this debian support thread for the help.
