Comment 4 for bug 1615286

I have the same problem with Linux Mint 18 XFCE. I just built a new HTPC and basically whenever I turn off the TV and turn the TV back on, the desktop will not return. However, I can bring up a tty. To get the desktop back I need to shh in and either restart mdm or use xrandr to reset the display mode. I could not get this to work so installed Linux Mint 18 MATE. Everything works fine with MATE.

The same display issue occurs when running LM 18 XFCE straight off of the install USB, so it's not some setting I changed.
