I also struggled with this bug when doing a fresh install of Mythbuntu 14.04 this week.
I downloaded xfce4-settings 4.11.0-1 from this link. https://launchpad.net/ubuntu/saucy/amd64/xfce4-settings/4.11.0-1ubuntu1 Then "sudo dpkg -i xfce4-settings_4.11.0-1ubuntu1_amd64.deb" to install it and synaptic to lock this version. I can now switch off my TV connected with HDMI cable and when I switch it back on it works. Mythbuntu is running on a Gigabyte Brix GB-BXBT-2807 with 4gb ram, 120gb ssd, DVB-T usb tuner. The machine runs both front and backend. -- 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
