Intel (Power Saving Mode) – use integrated graphics to render Ubuntu desktop. NVIDIA On-Demand – use integrated graphics to render desktop, but possible to offload specific apps via dedicated GPU. NVIDIA (Performance Mode) – use dedicated NVIDIA GPU to render Ubuntu desktop. Then you’ll see three options available in the right: When the app opens, navigate to ‘ PRIME Profiles‘. To switch GPU mode, search for and open ‘ NVIDIA X Server Settings‘. When done, restart your computer! Switch between NVIDIA and Intel Graphics:Īfter restart, your machine will be on performance mode with the dedicated GPU. There will be a little bar indicates the installing process. Then re-launch the ‘Software & Updates’ utility.Ĭhoose one of the drivers from the list and click on ‘ Apply Changes‘ to install it. 
If it shows nothing, press Ctrl+Alt+T to open terminal and run command sudo apt update to refresh package cache. There it should list all available graphics drivers. Make sure ‘restricted’ repository enabledĢ.) Next, navigate to ‘ Additional Drivers‘ tab.
