My old HP Pavilion is running 12.04. I want to be able to connect it to the Smart TV at home, it's from Philips, in case you wanna know.

Anyways, I use a VGA cable to connect it to the TV, then I go into Ubuntu System Settings. There I turn the TV ON and it displays a Ubuntu desktop on the TV.

However, I want it to show the same screen. I chose to have Mirror screens, it works, but after a few seconds (5-10), it goes back to the setting it was before, even if I execute it.

This is very annoying. Do anyone know what the problem can be? I've used different resolutions, but it doesn't help.

Do you have another Ubuntu PC you could try? That would narrow down whether the problem is with Ubuntu or your HP Pavilion. –  bntser Aug 26 '12 at 2:29
