I must have spoken too soon...last night the 1080p was working. Today morning when I fire up the LMCE
Any suggestions are welcome. Will update this thread with my results.
Whoops - forgot to warn you. After you get your xorg.conf right, copy it over the Pluto version in the same directory. At certain times, the xorg.conf gets overwritten with the Pluto copy. I'm not sure when it happens - I know one of the times is when AVWizard starts, but there may be other times as well.
I generally keep a copy off the machine as well, together with several other files, so that anytime the machine is nuked or upgraded, I have copies.
