So…what can I do? Neon is mostly Ubuntu 22.04 to most effects. Kernel is 6.2.0-36-generic.
The kernel in use should support RDNA3, I believe.
Edit: judging from the comment made a bit ago, it wasn’t the kernel or mesa, they were just missing the firmware. And yeah, that’ll do it. I remember being frustrated with my 7900xtx not working on Pop! before I pulled in the firmware back on release.
