mini-HOWTO for running X on PVR-350 TVOUT with FC2 

Step 1: 

Get this file: 

extract it somewhere and move it to:

chmod 444 ivtvdev_drv.o

Step 2:

get the latest PVR-350 xorg.conf file from 

and follow the instructions given there

If your "end user" mythtv project has been dragging out for many weeks now (like mine) you need to comment out the following line as older versions did not have this commented on the HOWTO website.

#        Load  "fbdevhw"

This is the error that results in /var/log/Xorg.0.log by not having this commented out:

Duplicate symbol fbdevHWEnterVT in /usr/X11R6/lib/modules/drivers/ivtvdev_drv.o
Also defined in /usr/X11R6/lib/modules/linux/libfbdevhw.a

Step 3:

I got an error about /dev/fb0 not existing in the /var/log/Xorg.0.log file ... doing 
the following made it go away:

Edit /etc/rc.d/rc.local and add

modprobe ivtv-fb

Reboot and you should see X windows running on your television. At least 
I did!  

Good Luck,


Here is my /etc/modprobe.conf file if anyone is interested:

alias char-major-61 lirc_i2c
alias eth0 via-rhine
alias eth1 prism54
options ivtv ivtv_debug=3
alias snd-card-0 snd-via82xx
install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-via82xx { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-via82xx
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd

# ivtv modules setup
alias char-major-81 videodev
alias char-major-81-0 ivtv
install ivtv /sbin/modprobe --ignore-install ivtv; /sbin/modprobe ivtv-fb

install lirc_i2c /sbin/modprobe ivtv; /sbin/modprobe --ignore-install lirc_i2c
