I have a Ryzen 2400G and a Asus x370 and run Ubuntu 18.04.1. The virtual machine is enabled in bios but it doesn’t seam to make a difference if it’s switched on or off. And I have two screens connected. I experience random freezes of the system. It looks like the graphics driver is crashing when playing a video via VLC or HTML5 in firefox. The odd thing is the audio playback resumes but the displays freeze. Very rarely I was able to still move the mouse but mostly that freezes too.
I found this when I searched for the error but the thread seams removed: https://wyldeplayground.net/ubuntu-18-04-crashes-randomly-on-amd-ryzen-2400-g-with-4-16-12-kernel/
Does anybody have the same problem or might know how to solve it?
Thanks for your help :)
