I recently made a post because I couldn't get my NVIDIA GPU up and running. This is the post: link to my other post. I got my gpu working now (through NVIDIA X server settings). These are my specs:
ubuntu version: 16.04.1
GPU: NVIDIA Corporation GM108M [GeForce 840M]
But every time I suspend my laptop and reboot it I get a black screen with this error message:
[ 5107.273042] usbhid 2-3:1.0: suspend error -5
[ 5107.644336] NVRM: Xid (PCI:0000:03:00): 79, GPU has fallen off the bus.)
[ 5107.644336]
The only solution there is is to completely reboot my laptop with the power button.

Thus, it only happens when my laptop puts itself in sleep-/suspend-mode (I deactivated that now so it doesn't go into sleep-/suspend-mode anymore). Powering up my laptop has no problems with this. Never encountered this before either. I also switched back to my Intel GPU to test if it still occurs, but it doesn't. So it has to do something with my Nvidia GPU.
