I am having the same problem. I upgraded frm Mythbuntu 12.04 to 14.04 with the Asus M3N78 motherboard (Nvidia 8200 graphics card & nvidia-304-updates driver).
Using xfce4-settings from Ubuntu 13.10 (as per post #18) fixed it for me. I have not tried using the suggestion from post #10. There is another fix in this thread that I'll try later this week -> http://ubuntuforums.org/showthread.php?t=2221496 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1308105 Title: Xfce resets TV mode to NULL when power cycled To manage notifications about this bug go to: https://bugs.launchpad.net/mythbuntu/+bug/1308105/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
