[mythtv-users] mythbuntu nvidia edid hdmi issues SOLVED

I just upgraded mythbuntu to 10.10 from 10.4 and it seems to have

appropriate screen resolution through X.  For whatever reason, no EDID 
information can be obtained from the current NVIDIA driver, and the 
get-edid utility did not work either, so there seemed to be no way to 
get the EDID information to provide to the NVIDIA xorg.conf file to deal

and ended up being able to use that file  in the [device] section of the 
xorg.conf file

Option "CustomEDID" "DFP-0:/etc/X11/edid.bin"

This not only fixed the X starting up issue, but also restored the 
ability to output sound through the HDMI port, as this apparently depends o
