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-X, which is subscribed to nvidia-graphics-drivers in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
