Very low performance with AMD Ryzen Pro 4750U

irvis · 04-19-2021, 07:22 AM

Hey,
Sorry to write it, but same here.
Tried on Ubuntu 20.04 and 20.10.
Drivers version tried 5.3.1.34 and 5.4.0-55.153.
Laptop:

Processor: AMD® Ryzen 5 pro 4650u with radeon graphics × 12
Graphics: AMD® Renoir

System:

Gnome Version: 3.38.3
Kernel: Linux 5.8.0-50-generic x86_64
OS: Ubuntu 20.10

All works good, until I plug in docking station. Then system seems to behave like drunk old man. I get out of nowhere latency between click and run program, each window is fragmenting once moving, unusable, not able to work on that

as I recall on Ubuntu 18.04 and 18.10 it was ok. So I suspect drivers.

Do you think this can be connected with issue described here

Hello,

We're all in the same boat.
I have shared my device details Here

Why my situation is explained Here

I hope DisplayLink can atleast make use of GPU for Linux users.

Looking forward for a fix.

Manjaro Team.

I have to same problem under Ryzen 5 3500u. The fix with the amdgpu drivers doesnt work here because the Radeon Vega Mobile Gfx is not supported. I had a problem with grafic glitches. Please fix these problems.

Are there any updates? Did your problems get fixed meanwhile?

Not for me. After digging thru tons of posts and googling for another day and waiting for any official response in this thread for a while, I gave up eventually and returned the docking station. Even if there is some way to fix it, I'm not buying a 200 Euro Docking Station in order to waste several days to set it up.

Are there any updates for AMD only machines?

Waiting, waiting for ages now... any updates?

@Displaylink you could take at least an opinion or position to that topic and not just ignoring this bunch of poor users.

How about treating your users with some dignity?
