NVIDIA doesn’t work with Wayland
As others have discovered, nVidia doesn’t play well with Wayland: Ubuntu 17.10 on Wayland - (How) can I install the NVIDIA drivers?. The solution is to switch to Xorg. To summarize the answer from cl-net use these steps:
-
To install the NVIDIA drivers, execute
sudo apt install nvidia-384. -
Additionally you can force the GDM login screen to use Xorg by default.
To achieve this, just executesudo nano /etc/gdm3/custom.conf.
Remove the character#from the line# WaylandEnable=false.
Now press Ctrl+X, then Y and Enter to save that change. -
Restart the Ubuntu operating system, execute
sudo reboot.
Another problem you will likely encounter is no sound over HDMI to external monitor. To solve this problem see this Q&A: No Audio Over HDMI on NVIDIA GeForce GTX 1050 Ti
