You are right Sebastian, this is far from solved. Just noticed yesterday something strange, was watching football match and decided to switch to the TV screen so i did as you adviced. To my surprise i could hear sound but could not see neither the match nor the browser window that was open. I then tried logging out and it took me back to the screen which you get when you click CTRL+ALT+F1.
Further to that, on the lite widget it displays my user name twice under "Logged in as". I had to restart the computer for it to properly work. So until a fix is found, i think now i have to look for keyboard shortcuts that will allow me to restart the computer without going through all the above process.
