I have a graphics problem and I don't know why, someone told me that Ubuntu does not have support for vega 8 graphics, and my PC has a 3200g Ryzen APU.

Frequently when changing frames (updating on a page or changing programs), horizontal stripes appear with parts of frames before the update, on other occasions they are black or white. This does not occur when I dual-boot into Windows.

    To start with, which version of Linux have you installed (Ubuntu server, Ubuntu desktop, Kubuntu, Lubuntu, Xubuntu, Ubuntu MATE, et al.) , and which release number? Are you using virtualization, and if so, which package? Please click edit and add that vital information to your question. Please do not use Add Comment. – K7AAY Feb 19 at 17:03

I found a solution here (panariga's "Workaround 2") with which I could keep the IOMMU enabled in the BIOS and without needing any custom drivers.

Workaround 2:

Add iommu=pt to kernel command line in /etc/default/grub:

sudo nano /etc/default/grub

Edit the line beginging GRUB_CMDLINE_LINUX_DEFAULT to look like this

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash iommu=pt"

Update GRUB:

sudo update-grub

Reboot

reboot
