How to switch into AMD integrated graphics from Nividia external graphics on ubuntu 20.04

us flag

So I wish to switch to my integrated graphics, that is AMD since my processor is Ryzen 7 5800 and it comes with 2GB integrated one. I have an external Nividia RTX 3060 but it is causing issues and obviously consumes more power which is not needed on ubuntu.

The last time I tried to switch to a AMD GPU on a different system, it messed up my system a lot so I am hesitant in taking steps and asking the question here.

Edit My system is dual booted, so I am using windows and ubuntu both. Now windows have a feature where it switches between the GPUs according to the need of the system. But on ubuntu, I would like to stick to AMD integrated ones since it consumes less power there by increasing the hours I get from the battery.

Any kind of help is appreciated!

Do you want to stop using the Nvidia card in all applications and OS s on the machine?

Well, I have dual booted the system. I would like to use it on windows but not ubuntu.

I think the feature you’re looking for is prime-select (provided by the nvidia driver):

sudo prime-select intel

Will disable the nvidia driver (after a logout):

nvidia-smi --loop=1
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

By default it should be on-demand:

sudo prime-select on-demand


nvidia-smi

Yes, and I could also do it by switching off the Nvidia drivers completely.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
