RetroArch can run without an X-server via DRM/KMS, but I doubt the snap package has permissions to do such a thing. Would it be possible to download and run an AppImage on there instead?

[kyvaith]

After some research, I think, to achieve that RetroArch snap package need to be build as a Ubuntu Frame (IoT) client.... https://mir-server.io/docs/developer-guide

[hizzlekizzle]

It's weird. RetroArch definitely works in wayland, and according to that doc, any wayland-compatible program should run fine :/

EDITed with debug build of RetroArch:

[gouchi]

@kyvaith Is this issue fixed since this PR has been merged ?

Thank you.

[viachaslavic]

Fix #57 solves the issue described by @kyvaith and now runs successfully in DRM/KMS mode on Ubuntu Core (but I could not pick up a working input driver on my VM)

But RetroArch cannot run on Ubuntu Frame even with the standard build https://github.com/libretro/RetroArch/issues/16730#issuecomment-2187578032. On Ubuntu Desktop 20.04 i can run RetroArch version 1.7.3 on Ubuntu Frame. But last commits worked on Weston, Sway but not Ubuntu Frame. @hizzlekizzle maybe it makes sense to create a separate issue for running on Ubuntu Frame?

Sure, go for it :)
