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.
