how to install nvidia-driver-450 on debian 11?


on the same machine I have nvidia-driver-450 installed under ubuntu 20.4.
Anyway I like it because PRIME profiles works and allows me to change to Power Saving mode that makes my battery last longer.

now on this machine but on Debian 11, i had nvidia installed but I just cannot find PRIME profiles that allows to switch to Power Saving mode.
Just now I apt remove nvidia*
now, if I could do "apt install nvidia-driver-450" then i may get PRIME working, but it does not work.

Right now, under debian 11 and this brand new laptop, I only have 2 hours
of battery life. I think the battery probably longer if I boot to Ubuntu. Under ubuntu, it reports fluctuating numbers like 7+ H, 4+H, and 2+H, which I think
might have to do with the load at that time and probably average to 3.5H, still better than the mere 2H on debian.

but I cannot locate PRIME to switch to Saving Power mode. I want to minimize power usage.

What is "PRIME"? I do not see such thing in NVIDIA settings.

The only thing I see somewhat related is PowerMizer, and mine is a desktop card.

No such thing as "PRIME" on my system. Just the normal "NVIDIA X Server Settings".

You probably have a laptop with CPU graphics and a GPU. Check your settings in the BIOS. And state what machine you have so people reading this thread can have a clue of what is going on and help you accordingly.
