I can also confirm this bug. Moreover, the nouveau driver does not have
this bug. Can I help fixing it somehow?

Display backlight won't turn on after screen timeout
Status in nvidia-graphics-drivers-367 package in Ubuntu:
Using nVidia driver 367.44 on Skylake Intel Processors, with 1000
series graphics, the backlight won't turn on after turned off by gnome
session idle delay (org.gnome.desktop.session idle-delay). or by `xset
dpms force off`
Resume from suspend is unaffected.
This is on a clean install of 16.10 with the 367.44 nVidia driver.
This is a regression from the 367.35 driver. 367.48 and 370.28 also
exhibit this behavior.
This is confirmed on the following hardware:
Oryx Pro 2 (oryp2) i7-6700HQ with 1070
Serval 10 (serw10) i7-6700 with 1060
Bonobo 11 (bonw11) i7-6700K with dual 1070
Steps to reproduce:
1. Install a fresh image of Yakkety and 367.44 from the graphics driver
2. Log in to Unity shell
3. Lock screen and wait for dimming.
4. Move the mouse to 'resume'
5. The screen will turn on, but the backlight is still off
The current workaround:
1. Hit tty1 (Ctrl+Alt+F1)
2. Hit tty7 (Ctrl+Alt+F7)
This will bring Unity back to life.
