Bug Description
Just installed Linux Mint 18 with XFCE (reformatted the partition, but recopied some files from ~/.config); previously using Linux Mint 17 with KDE and no related issues. I am using mdm. I have an i3 with Intel HD Graphics 4400, and a standard LCD monitor connected via HDMI to my desktop PC.
If I turn my display off, due to any of the following:
- Configuring "Blank after X minutes" in Power Manager and waiting for X minutes;
- Physically pressing the "power off" button on my monitor;
- Suspending and then resuming my session;
Then, when turning the screen back on, it does not work anymore: everything is black, and after a few seconds the monitor reports "no signal".
Keyboard and mouse still work, I can toggle the Num lock light on the keyboard, for instance, and switch via Ctrl+Alt+F1 to a terminal. If I do so and run "xrand -d :0.0 --auto" (as recommended in one forum for an user having similar issues), I get "xrandr: Configure crtc 0 failed". If I try the exact same command before turning the screen off (also using a Ctrl+Alt+F1 terminal, for instance), I get no message, but because the screen is already on, nothing happens.
I tried looking at dmesg and /var/log/syslog to find relevant error messages, but nothing seems immediate to me. I can try using other display managers or anything else that can help debug the issue.

I"m running xfce through Xubuntu 16.04 and this same problem starting showing up for me about a month ago. My display is a tv connected through hdmi. When I log in using a Unity desktop, rather than xfce/xubuntu, I don't have this problem.
