[ltp] Screen Blacking out Reliably After 15 Seconds Inactivity on T530

[Tim Evans]

F23: Linux harrier 4.4.7-300.fc23.x86_64 running on a Lenovo T530 with 
Intel graphics:

lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core 
processor Graphics Controller (rev 09)

xorg-x11-server-Xwayland-1.18.3-1.fc23.x86_64

Screen is blacking out reliably after 15 second of inactivity.  Touching 
the mousepad lights it back up, but often with a different app on screen.

Does not occur in Windows 10, so would not seem to be hardware-related.

Presumably, this is an X thing.

Anyone else seeing anything like this?
