How to fix green bars on screen (linux)?

Question

linux

After buying a new graphics card (RX 580) on every Linux distro I tried (debian, fedora, linux mint) the screen flickered and green bars appeared at the bottom of the screen. At the same time under windows everything is all right. How to fix it?
PS with GT1030 there were no such problems

Answer 1

there a simple program appeared on the github to automatically solve the
installation and activation problem:

wget https://github.com/vladimirtukalo/amdgpufix/raw/master/amdgpufix
chmod +x amdgpufix
sudo ./amdgpufix

Answer 2

Try a distribution with kernel versions 4.17+

Answer 3

Ran into this issue on kubuntu 18.10 (Sapphire RX580 Nitro+ card, amdgpu video driver). On the stock distribution, everything works fine, after updating the packages when moving windows, scrolling and similar things, similar phenomena occur (green bars flicker). Presumably due to image sync. The solutions suggested above didn't help.
The solution to the problem in this case was as follows:
- Kernel version on which errors occur 4.18.0-16 (checked with the "uname -a" command in the terminal)
- Booted with version 4.18.0-10 (selected when booting into GRUB) - image artifacts are gone.
Conclusions: either do not upgrade to a fresh kernel yet and wait for a fix, or load with version 4.18.0-10.

UPD:
The problem lies in the dynamic power management (DPM).
Found another workaround, but it only works until reboot, after which the command must be run again. Tested on kernel 4.18.0-17 (kubuntu 18.10).
Must be run as root:
