AMD Ryzen™ 5 3400G drivers for Ubuntu (can't change screen resolution)
Solution 1
I just bought the new 3400G and I run into the same problem
https://github.com/M-Bab/linux-kernel-amdgpu-binaries
Clone or download -> Download zip
sudo dpkg -i [linux-headers-name].deb [linux-image-name].deb firmware-radeon-ucode_*_all.deb
sudo update-grub
sudo reboot
Thats it I would like to give the kiss to whoever make that available man
Solution 2
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.
Solution 3
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.

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 toxrandr
, but none worked.
