on amd radeon r2 (with amdgpu drivers) it does not run gamescope through sddm, black screen and then it returns to sddm

pachof commented 10 months ago

It doesn't want to run the gamescope session in sddm but in kde it runs without any problem

What card exactly?

pachof commented 10 months ago

I got confused, it's not a Radeon R9, it's a Radeon r2, exactly the amd Radeon r2 with e1-6010

If anything is Sea Islands, it is the architecture. And when running in KDE, gamescope runs without problems but when run from sddm it does not start

MetalfaceScout commented 8 months ago

I also have this issue, with the Radeon R7770 (Southern Islands). I put amdgpu.si_support=1 in the kernel args but still not working.

3ap commented 6 months ago

I ran into the same error with my Radeon RX560. Here's what I found in the /run/user/1000/gamescope-session.log:

My computer is running HoloISO. Here’s the output from uname -a:

If you need more information, just let me know.

UPD: Forgot to mention that I need to use amdgpu.dc=0 to make GPU work on any system (incl. Ubuntu 20.04, 22.04, Arch Linux 2020+, etc.). Maybe this is the root of the issue.

3ap commented 6 months ago

I made a simple C program and shared it in a gist to show the issue I'm facing. To get it to run on my system, I had to switch from /dev/dri/card0 to /dev/dri/card1.

Here’s the gist: https://gist.github.com/3ap/db40f820e42454347361159d27509cd3

When I run the program, this is what I get:

drmSetClientCap(3, DRM_CLIENT_CAP_ATOMIC, 1) = -1
errno = 95

The error code 95 stands for EOPNOTSUPP.

According to the documentation at https://dri.freedesktop.org/docs/drm/gpu/drm-uapi.html#c.DRM_CLIENT_CAP_ATOMIC:

If the driver doesn’t support atomic mode-setting, enabling this capability will fail with -EOPNOTSUPP.

Does this mean GameScope will never work for me?

misyltoad commented 6 months ago

Polaris should be AMDGPU kernel driver, and should support ATOMIC just fine. You must have done something weird with your setup.

misyltoad commented 6 months ago

Oh, amdgpu.dc=0, yes you need AMDGPU DC for atomic to work. You are correct that that is the root cause of the issue.

pachof commented 6 months ago

sorry for not responding in time, I was in my studies, I'm going to try that script and that commandline

ValveSoftware / gamescope

on amd radeon r2 (with amdgpu drivers) it does not run gamescope through sddm, black screen and then it returns to sddm #1094
