Dell 15 SE (5505) does not detect Radeon 5600M with F33

Greetings!

I have recently purchased a Dell 15 SE. Its an awesome machine, on paper. I am attempting to get my dedicated graphics card working. The machine works okay for playing Baldur’s Gate EE, but I can’t play anything more demanding. So I started investigating and it looks like the 5600M is not being detected.

[dustin@razorback ~]$ xrandr --listproviders
Providers: number : 0

I’ve added pcie_port_pm=off:

I’ve also installed i8k for better cooling.

[dustin@razorback modprobe.d]$ cat /etc/modprobe.d/* | grep "i8k"

Thank you for taking a look!

Hi there, here’s an update to this issue. I have updated to 5.9.12 and have tried all combinations of amdgpu.runpm=0 (present and not) and pcie_port_pm=off or =forced.

I have disabled PowerNow in the bios, but im still not able to game. Here is a little more info on the kernel and what xrandr says.

I notice the following in my dmesg:

Okay! I’ve fixed it. The trick was to remove the “nomodeset” parameter. Here is what im using to boot.

# grubby --info /boot/vmlinuz-5.9.12-200.fc33.x86_64 
index=0
kernel="/boot/vmlinuz-5.9.12-200.fc33.x86_64"
args="ro rootflags=subvol=root rhgb quiet $tuned_params amdgpu.runpm=0 pcie_port_pm=off iommu=soft"
root="UUID=98a08706-ee0e-4959-bd77-0ff61c7c2fc5"
initrd="/boot/initramfs-5.9.12-200.fc33.x86_64.img $tuned_initrd"

id="a74a946993794db8b5333a3fb1e2d953-5.9.12-200.fc33.x86_64"

Here’s more information on setting the boot parameters:
