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

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 team's PPA. 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.
