AMD Ryzen 3 2200G on Ubuntu 18.04
New PC i have purchased have AMD Ryzen 3 2200G CPU. This come with Vega 8 iGPU.
If you boot Ubuntu 18.04 on this PC, it fail to boot with some graphics errors. To boot, you need to select advanced option, then recovery, once you get in the menu with differnt options, select continue. This will boot PC with out hardware acceleration.
You can also set “nomodeset” in /etc/default/grub
Find
|
1 |
GRUB_CMDLINE_LINUX_DEFAULT="" |
Replace with
|
1 |
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset" |
Now run
|
1 |
update-grub |
But doing this disable hardware acceleration. Proper way is to install AMD drivers. You can use open source or AMD propritery, i dedided to go with AMD propritery drivers.
Install Latest Kernel
Support for Vega 8 iGPU only available in latest kernel. So you need to install latest kernel from ubuntu mainline.
Go to
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D
Find the latest kernel, it will be listed on top of the page. At the time of writing this post, it is “v4.19-rc5”
Click on this folder. You need to download 3 files with name generic for amd64 and install it.

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19-rc5/linux-headers-4.19.0-041900rc5-generic_4.19.0-041900rc5.201809231830_amd64.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19-rc5/linux-image-unsigned-4.19.0-041900rc5-generic_4.19.0-041900rc5.201809231830_amd64.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19-rc5/linux-modules-4.19.0-041900rc5-generic_4.19.0-041900rc5.201809231830_amd64.deb |
Install it with
|
1 |
sudo dpkg -i *.deb |
Install AMDGPU PRO driver
I don’t really know how to find latest driver from AMD site. It only lists Windows deivers. I had to use google to find link to latest AMD driver.
With some googling, i found a driver released on August 17th , 2018
https://www.amd.com/en/support/kb/release-notes/rn-prorad-lin-18-30
On this page, you have download links for differnt linux distributions, for Ubuntu, i run
|
1 2 3 4 |
wget https://www2.ati.com/drivers/linux/ubuntu/18.04/amdgpu-pro-18.30-641594.tar.xz tar xvf amdgpu-pro-18.30-641594.tar.xz cd amdgpu-pro-18.30-641594 ./amdgpu-pro-install |
amdgpu-pro-install is actually a symlink to amdgpu-install, but you should run “amdgpu-pro-install” to install the driver as it will run amdgpu-install with –pro switch.
Now reboot your PC, your iGPU will work.
Before installing new kernel, glxinfo reported following

If you don’t install newer kernel, amdgpu-pro-install install will FAIL, i get some segmentation fault.
