Unable to use scrcpy with AMD graphics in Linux

[heurekus]

Environment

• OS: Ubuntu 20.04
• scrcpy version: 1.18
• installation method: snap
• device model: S21
• Android version: 11

Describe the bug

when launching scrcpy from bash I get the following error message. There are similar reports for other projects citing amdgpu.ids not accessible from snap packages due to Apparmor restrictions. Perhaps that's the same thing here. Note: I have a notebook with Ryzen 7 CPU 4750U with AMD GPU obviously:

x@x:~$ scrcpy

Try a non-snap version.

[heurekus]

Would like to but can't do it on this machine. Unfortunately that's the only AMD Ryzen machine I have.

[heurekus]

Idea: I will boot from USB later and do it there. Will let you know.

[heurekus]

I tried the non-snap version on an Ubuntu 20.04 installation that did not have a scrcpy install so far on the notebook with AMD CPU/GPU.

I did the following:

• did a 'snap install scrcpy' to see if it would work on that machine. Result: Same error as above
• reboot + install via recommended quick procedure (git clone + install script): Result: scrcpy works. Uninstalled again.
• reboot + another snap install to see if the direct install might have done something good: Same error again as above.

So it looks like the snap security profile does not allow access to the AMD GPU specific stuff or the snap package is missing it.

--> everything is working --> uninstall and reboot afterwards with the provided script. Left packages installed with apt as they were.

Guys, the problem is the following:

/usr/share/libdrm/amdgpu.ids: No such file or directory

I had a look and the file is part of your snap distribution. However, the snap yaml file does not contain it in the libraries path so it is not available inside the snap container. Could you please have a look at the snap yaml file, put this path (XXXX/usr/share/libdrm) and then check whether amdgpu.ids is accessible inside the snap container? That should do the trick :)

You can check if it's mapped inside by logging into the snap container:

snap run --shell scrcpy

@heurekus, thanks for the suggestion. Added a bind to libdrm.

Please install the snap from the edge channel and see if this solves the issue.

Thanks.

[heurekus]

@sisco311 Wow, yes, it works again now! Cool, thanks!

[sisco311]

No problem.

Applied the fix to the versions from the beta and stable channel.

[shouryade]

Currently using the stable channel doesn't still work, and throws up the same error. @sisco311 please look if the fix has been properly applied. The edge channel runs perfectly though. scrcpy version 1.24

how can i downgrade snap ?? now 1.25 to 1.24 with amd same issue fedora 37

[agentzhao]

Same issue here. Stable channel doesn't work but edge channel is working for me.

[heurekus]

Hey! Just gave this a try right now, and v1.25 from the stable channel unfortunately still does not have the fix. Then removed and installed v1.21 from the edge channel. This still works but unfortunately, as Android progresses, v1.21 becomes less and less useful. Would be great if the fix made it into the stable channel as well :)

@heurekus Try uninstalling the snap version and installing the latest version manually: https://github.com/Genymobile/scrcpy/blob/master/doc/linux.md#latest-version

[heurekus]

Hi rom1v. Many thanks for the tip! I installed the latest version (v2.2) on Ubuntu 22.04 today (git clone, etc.) and this version is working fine with AMD CPUs. Great! I had no idea that the (unofficial) snap package 1.25 is sooooo far behind. Cheers! :)
