Adding NVIDIA Driver DKMS Support to 4.18.X Kernel
As of July 2018, new Linux kernels had made some changes causing incompatibilities with Nvidia proprietary drivers. This can be fixed easily by applying a patch to the Nvidia DKMS code to properly expose features in the DRM, which will allow the DKMS to build properly.
Download and install the Nvidia drivers from the graphics team ppa
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
apt-get install nvidia-390 nvidia-dkms-390
The DKMS portion may fail to correctly build the DKMS for your 4.18 kernel. If it does, apply the nvidia-drm-drv.c file.
cp razerfiles/nvidia-drm-drv.c /usr/src/nvidia-390.67/nvidia-drm/nvidia-drm-drv.c
sudo dkms build -m nvidia -v 390.67 -k $(uname -r) -a x86_64
sudo dkms install -m nvidia -v 390.67 -k $(uname -r) -a x86_64
