Ubuntu 20.10 has a nice new feature when it comes to managing graphics drivers.
Use the following to see what drivers are available and which is recommended:
ubuntu-drivers devices == /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 == modalias : pci:v000010DEd00001C03sv00001043sd000085A4bc03sc00i00 vendor : NVIDIA Corporation model : GP106 [GeForce GTX 1060 6GB] driver : nvidia-driver-450 - distro non-free driver : nvidia-driver-460 - distro non-free recommended driver : nvidia-driver-460-server - distro non-free driver : nvidia-driver-450-server - distro non-free driver : nvidia-driver-418-server - distro non-free driver : nvidia-driver-390 - distro non-free driver : xserver-xorg-video-nouveau - distro free builtin
Then if you are happy with the recommendation:
sudo ubuntu-drivers autoinstall
It seems like a good idea to run this after every dist-upgrade.
