Bug Description
I use my system connected to a TV screen via HDMI. The TV screen is also used as a regular TV, input selected to be either HDMI or "antenna". After upgrading to 14.04 LTS, after a while of watching regular TV and going back to HDMI display, the TV reports "No signal". I try to revive by moving the mouse or press the keyboard, but nothing happens. I try to reconnect the HDMI cable, but no change. The keyboard and mouse are wireless with a USB reciever/
I have tried to set the screensaver and power manager so that the computer never idles, but there is no improvement.
I have had some trouble with the NVIDIA driver, the HDMI sound configuration is not stable. HDMI sound units come and go between boots. Maybe it is connected.
Nothing of this happened in the previous release, 13.04LTS.
The desktop display was readily available after setting the HDMI input selector on the TV after watching regular channels.

I realize that the tagging is incorrect, nothing is wrong with the release upgrader utility as such.
My point is that the bug is related to the new 14.04LTS distribution, which is not the same thing.
Please change it to something more suitable, I am not sure what it should be.
