Hello All, I need help please :
I have a GPD WIN 4 7840 and a dock with RTX Nvidia 4070
The HDMI from my TV is on the RTX
When I try to play on TV, I have both screens but when I try to launch a game (Like PES 2021) the system detect only the 780M (Internal GPU)
How to choose the EGPU on primary when the GDP is docked ?

I know with an AMD card you could use

DRI_PRIME=

DRI_PRIME=

but I've no idea if that works for Nvidia.

Kamquat•7/6/24, 4:47 PM

In terminal, type

 DRI_PRIME=1 glxinfo | grep renderer

 DRI_PRIME=1 glxinfo | grep renderer

and then do

DRI_PRIME=0 glxinfo | grep renderer

DRI_PRIME=0 glxinfo | grep renderer

Kamquat•7/6/24, 4:47 PM

See if they give different results or not

Are you using a -deck build?

LulufcmOP•7/6/24, 4:49 PM

What did you mean with deck build ?

Kyle Gospo•7/6/24, 4:49 PM

We ship switcheroo which should use your dGPU automatically, no need for prime

LLulufcm What did you mean with deck build ?

Kyle Gospo•7/6/24, 4:49 PM

Do you have game mode?

Kamquat•7/6/24, 4:49 PM

I get to start dealing with new eGPU issues later today, my 7600m is showing up from Amazon.

Kyle Gospo•7/6/24, 4:49 PM

It boots to steam big picture?

KKyle Gospo It boots to steam big picture?

LulufcmOP•7/6/24, 4:50 PM

yes on the GPD and when I switch to Desktop I see my TV with the RTX HDMI

LLulufcm yes on the GPD and when I switch to Desktop I see my TV with the RTX HDMI

Kyle Gospo•7/6/24, 4:51 PM

No deck build ships with Nvidia proprietary drivers at this time

Kyle Gospo•7/6/24, 4:51 PM

So you're using nouveau with nvk

Kamquat•7/6/24, 4:51 PM

So it's probably using Nouveau in desktop. You should just be able to rebase

Kyle Gospo•7/6/24, 4:51 PM

Which is very, very early Software

KKamquat So it's probably using Nouveau in desktop. You should just be able to rebase

Kyle Gospo•7/6/24, 4:51 PM

Then they lose game mode

Kyle Gospo•7/6/24, 4:51 PM

And HHD

KKyle Gospo Then they lose game mode

Kamquat•7/6/24, 4:51 PM

Ohhh snap yeah its a GPD

Kamquat•7/6/24, 4:51 PM

my bad

Kyle Gospo•7/6/24, 4:52 PM

The simple fact is: we do not support Nvidia dGPUs on handhelds

Kyle Gospo•7/6/24, 4:52 PM

Sorry

LulufcmOP•7/6/24, 4:52 PM

yes GPD not Steamdeck

Kyle Gospo•7/6/24, 4:52 PM

Too much wrong with them

LulufcmOP•7/6/24, 4:52 PM

so this is not possible to work ?

Kyle Gospo•7/6/24, 4:52 PM

Correct

Kyle Gospo•7/6/24, 4:52 PM

An AMD one would be fine

Kamquat•7/6/24, 4:53 PM

Not in any simple way at least (you could probably do insanity with VFIO, but...)

Kamquat•7/6/24, 4:53 PM

I wouldn't want to do it on a eGPU w/ handheld.

LulufcmOP•7/6/24, 4:54 PM

On Windows it work very good

LulufcmOP•7/6/24, 4:54 PM

but SteamOS is better for Gaming

Kyle Gospo•7/6/24, 4:54 PM

Nvidia's proprietary drivers do not support game mode, they've had years to fix this

Kyle Gospo•7/6/24, 4:54 PM

Unfortunately it's on them

Kyle Gospo•7/6/24, 4:54 PM

Nothing we can do

Kamquat•7/6/24, 4:54 PM

Nvidia often has issues on Linux, because only Nvidia can do anything to fix problems.

Kamquat•7/6/24, 4:54 PM

and they don't.

LulufcmOP•7/6/24, 4:55 PM

ok so the problem is Nvidia not the oculink ;D

matt_schwartz•7/6/24, 4:55 PM

time to put steamos on my nvidia rig and make a clickbait YouTube video about steamos supporting nvidia now

LLulufcm ok so the problem is Nvidia not the oculink ;D

Kamquat•7/6/24, 4:55 PM

Yes. Nvidia would work on a desktop image, but you'd lose game mode.

Kamquat•7/6/24, 4:55 PM

and on a handheld you probably don't want that.

KKamquat Yes. Nvidia would work on a desktop image, but you'd lose game mode.

LulufcmOP•7/6/24, 4:56 PM

ok so It can work
If I understand, when Im on my TV I can launch game with Oculink and RTX but not in game mode ?

Kyle Gospo•7/6/24, 4:56 PM

Desktop images don't have game mode or HHD

LulufcmOP•7/6/24, 4:56 PM

in Handled it doesnt matter because I never play on Handled with oculink

Kyle Gospo•7/6/24, 4:57 PM

So you won't have any game mode at all, and the input on your handheld won't work properly

Kamquat•7/6/24, 4:57 PM

No, there's two sets of images. One for desktop and one for handheld ( bazzite-deck images)

Kamquat•7/6/24, 4:57 PM

what Kyle said yea

Kyle Gospo•7/6/24, 4:57 PM

It's not worth rebasing for the docked GPU

LulufcmOP•7/6/24, 4:57 PM

Kamquat•7/6/24, 4:57 PM

you'd basically have to leave it docked all the time and use a BT controller. Not worth.

LulufcmOP•7/6/24, 4:57 PM

So any solution

LLulufcm So any solution 😦

Kyle Gospo•7/6/24, 4:57 PM

You would have to make a custom bazzite image, or use a different distro

Kyle Gospo•7/6/24, 4:58 PM

I'm sorry, we just do not support your use case
