Difficulty using the NVIDIA GPU
Hi, I'm a new Linux user. Kubuntu is my first experience with it. I have problems with the dedicated NVIDIA GPU. Apparently, it is not being used correctly. I installed the driver suggested by “Additional Drivers” (i.e. NVIDIA driver metapackage nivdia-driver-560). I have Envycontrol installed.
I really need some help. My knowledge of the subject is exhausted.
Kubuntu is installed on the SSD and is the only operating system.
