Just got my optimus-manager installed - need howto on settings

Support Graphics & Display

I have read all the wiki’s and some support posts but I am still not clear on how I should set the settings in the optimus-manager-qt package.
What is the best settings for performance, battery and power settings?
Should I have it set up for Auto switching and how do I test that it is working?
Here is my inxi for graphics:
Does this look right?

One of the more knowledgeable members suggest avoiding it

OK I must be dumb as a box of rocks.
The discussion you lead me to on one hand says that I should use bumblebee but on the other hand indicates that bumblebee is outdated or old or going to be obsolete.

What is the final conclusion on all of this?
If I understood it correctly Manjaro devs are going to remove optimus-manager?

Ok this article talks about all the choices:
https://wiki.archlinux.org/title/NVIDIA_Optimus

What I would ideally like is to let the computer decide which application uses nvidia or intel graphics.

I don’t know what package is best suited for which card.
Is there somewhere that tells me this?
Thanks

No it doesnt.
It is simply taken from a thread in which the user had an old enough nvidia to necessitate bumblebee. So the discussion mentions bumblebee. It makes no statement that a modern nvidia should be using bumblebee.
If your nvidia card isnt ancient by nvidia standards then you should use PRIME.

Not going to happen.
No ‘solution’ will offer you this.
But you Can make sure certain applications always work on the nvidia.
More on this later if needed.

Use the highest available driver profile, also noting the no number is the latest.

If new enough that means

video-hybrid-intel-nvidia-prime

Now with PRIME your system is already in Hybrid mode. No ‘switcher’ tool needed.

Your system will run on the iGPU and only use the dGPU when you run prime-run.
ex;

glxinfo | grep 'renderer string'
prime-run glxinfo | grep 'renderer string'

Now on to ‘optimus-manager’ and the like.

As mentioned above … no such switcher utility is required.
The ONLY reason you might want one is if you want to be able to boot into iGPU (intel) alone, or dGPU (nvidia) alone. Not hybrid.

IF you do need such a switcher tool … please do not use the hot garbage that is optimus-manager. envycontrol is at least more reasonable.

Thank you . That at least clears up some of my confusion on this matter.
