GPU - How to disable integrated GPU and use Discrete GPU only

English Hardware
1

Since the last updates (mesa, nvidia etc…) I got some issues with my GPUs. I can’t have videos in full screen or my games don’t launch (DX11 resolution change issues).
I checked the forums and it looks like it could be related to my integrated GPU being used instead of my RTX4090.

Is there any way to disable, for good, this Radeon GPU? I have absolutely no use for this GPU with my setup and I would prefer to have it totally disabled.

Devices:

GPU0:
apiVersion = 1.3.277
driverVersion = 550.144.3.0
vendorID = 0x10de
deviceID = 0x2684
deviceType = PHYSICAL_DEVICE_TYPE_DISCRETE_GPU
deviceName = NVIDIA GeForce RTX 4090
driverID = DRIVER_ID_NVIDIA_PROPRIETARY
driverName = NVIDIA
driverInfo = 550.144.03
conformanceVersion = 1.3.7.2
deviceUUID = ae4b6b1e-1a5e-c39b-ebd8-e3639206370c

You’d need to look up the documentation for your motherboard/BIOS and go disable it in there, most likely.

Thank you, but I don’t have the option in there.

install suse-prime
and set it to nvidia
there is also a handy KDE plasma widget for this for the toolbar

Which device?
This is difficult to laptops.

I checked suse-prime, but it is X11 only.
However, I did not know about that widget, I will try it. Thank you!

Thank you to everyone who tried to help.

I reboot my system every night and this morning, after 2 days of issues aka 3 reboots, I launched a game to gather some logs and it just worked … Actually everything works, as smoothly as it always does with Opensuse, at least for me :slight_smile:

I am fairly new to Linux having moved from Windows 6 months ago so I am not clear about what and why it happened but 3 reboots after the nvidia/mesa updates did the trick :slight_smile:
