OS only runs on the dGPU
Former Windows power user here on an A. I was excited to check out Bazzite. Most of my hardware, including the more obscure stuff, managed to run fine. However, when I looked at Resources, I realized the iGPU (AMD 680M) was at 0% use, while the dGPU (3060) was always being used. When I looked up this issue, I had most people be in the opposite situation (iGPU always running, dGPU not working). I'm used to troubleshooting on Windows, but being fresh into an OS sure complicates things.

here is my fastfetch output
You've probably got a laptop with mux, need to use supergfxctl
Which is included
I do! But when I list my modes, only this shows up
Hmm, that mode should be automatic
Is what you're seeing while you're on the desktop?
yes
no games are running
Try closing steam for me if it's open
And maybe use nvtop
To check the usage
very interesting
no, no use on the iGPU even after closing steam
Try
switcherooctl list
So that's correct
See environment under the IGPU there?
Try prefixing steam with that and running it in the terminal
Then check if your IGPU shows usage
Could be a reporting bug
what is prefixing
Ie:
DRI_PRIME=bla steamI can't find where my steam install is
You just run steam
No need to path to it
no, no activity
Let me check my BIOS to see if Windows wasn't overriding anything
So with that command Steam would not be able to use any GPU other than your IGPU
It's quite possible this is a reporting bug
Might be worth retrying that, but with an actual game
Since it would be obvious to see your performance isnt good
Just close steam, run that same thing, and then launch a game
I will try
shouldnt you use dri_prime from the switcheroo
Oh yeah this too, that's what I meant by prefixing
My command was an example
it uses the 3060
you can even see when I tab out to take a screenshot
I guess bla skips the pathing?
It would just do nothing because that doesn't exist
You were supposed to replace that
with what, exactly?
environment here
oh, I put the exact environment variable and then type steam
Yes
it still uses the 3060
I think I wrote the command correctly this time
Yep, that looks correct
I'm not sure what's going on here, what you're posting should not be possible
My best guess is it's a reporting bug
How do I report this bizarre situation
What a shame. I was looking forward to nuking my windows install so dual boot it is
Running on the iGPU gives me 5-6 hours of battery life, and that's why I picked this laptop in the first place

Describe the bug I try to use my iGPU, but I fail regardless of what I do. Even running a program by prefixing my iGPU's environment variable does not work. It runs on my dGPU instead. What did...
