VGA disconnect reconnect, screen goes blank - thoughtinstinct - 11-07-2016
After upgrading to LL 3.2 whenever i disconnect VGA cable in order to connect the TV screen ( through VGA connection ) the screen goes blank and i have to restart the computer. This never used to be a problem before, how can i fix this?

Seems to be same as my problem.

Try CTRL+ALT+F1 after having plugged in the TV through VGA. If you see the login prompt, login and then "startx".
Obviously, this needs to be fixed.

I would suggest removing the SOLVED tag as this hasn't been solved. The fix I told is just a temporary fix that need to be reapplied for each disconnect (and each time the screen goes into powersave mode), and I think unless there is a permanent fix, this isn't solved.

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.
