On the official website of AMD I couldn't find the drivers for Ubuntu, only for Windows 10 (AMD Ryzen 5 Driver). I can't change my screen resolution, just one option available.

I tried a lot of things; I don't have the /etc/X11/xorg.conf file probably because I can't install AMD drivers. I tried a lot of commands related to xrandr, but none worked.

  • Welcome to Ask Ubuntu. Unfortunately not, there's a lack of Ryzen support in Linux world for some reason it takes AMD too long to release an official driver for Linux. You can read these articles about AMD open source drivers.

  • I recommend you to use pre-installed Ubuntu configuration. Or read through the documentation in my previous comment.

  • This CPU/APU has only just come out and will need kernel support I suspect....

I had similar issues with AMD Ryzen 5 3400g and Ubuntu 18.04. In my case I also wanted to connect second display. I spend hours working on the bios and different drivers to no avail. Finally I found the solution, just upgrade the kernel above 4.15. At the time of writing I managed to upgrade the kernel to 5.0. It really helped, I can change resolution and connect multiple displays.

To check what kernel you have:

uname -a

To upgrade kernel:

sudo apt install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04

Finally reboot the system.

Neither upgrading to 5.0 nor installing the linux-kernel-amdgpu-binaries linked above worked for me. I finally got my system running as expected after installing the 5.4.12 kernel using ubuntu kernel utility tools and NOT installing any additional drivers under Ubuntu 19.04.
