Drivers for RX550

[Trendkill]

Hi,

I'm running a system with amd ryzen 3600 and RX550 graphics. I would like to know what packages, modules and Xorg config i need to set to have a full desktop working with freebsd 12.0.


I have tried drm-fbsd11.2-kmod with amdgpu without succes (had problems with artefacts) and radeonkms.ko does not start xorg.

Is that actually possible to install drm-fbsd11.2-kmod with FreeBSD 12?

What artifacts?

What artifacts?

A bunch of colors in the screeen and everything freezes. I could not boot after that.

Did you happen to load amdgpu through /boot/loader.conf by chance?

I have added this line to my /etc/rc.conf
kld_list="amdgpu"

But this results in artefacts.

What about hw.syscons.disable=1 workaround then?

I thought for ports you want to point to the actual module. What you are loading with that command is the module in /boot/kernel
The base system has the same exact file name, so you must use the path to the module for some ports.

/etc/rc.conf
kld_list /boot/modules/amdgpu.ko

The book also says the same:

There is only linuxkpi-based port, amdgpu is around 4-5 years old and it never was in base.

I thought for sure I saw the module in /boot/kernel
But it was only amdgpio.ko that fooled me.

So the i915kms and radeon driver are the graphics ports modules that need the full path.

thank you guys for the suggestions but i solved using xorg driver 'scfb'. Now it's working.
