Trouble getting amd dedicated graphics to work on my dell inspiron 14

palwd · 2021-10-20 18:43:06

I have a dell inspiron 14 3480 laptop, and I am having issues with getting the dedicated graphics to work on my laptop.
So far I've just been using the integrated graphics.
The laptop I have a Radeon 520 which has the GCN 1 architecture and so following the arch wiki on amdgpu I have:

made sure Southern Islands support is enabled
I have specified the correct module order

set the required module parameters

options  root=/dev/nvme0n1p3 rw radeon.si_support=0 amdgpu.si_support=1

but my lspci ouput shows that the modules aren't being used.
output of lspci -k:

00:02.0 VGA compatible controller [0300]: Intel Corporation WhiskeyLake-U GT2 [UHD Graphics 620] [8086:3ea0]

        Kernel modules: radeon, amdgpu

here is my dmesg output:

I can't figure out why it isn't working.
Any help would be appreciated.

Try adding

DRI_PRIME=1

as a environment variable. ( it will force applications to use discrete card)

 sudo vim /etc/environment

DRI_PRIME won't help, things go south on a lower level.

Please post the full output of lspci -knn .
Also run as root journalctl -b | curl -F 'file=@-' 0x0.st . It will output a link , post that link.
