That would be surprising since I can SSH to my machine and everything works= perfectly beside the screen not receiving any signal.

I've tried adding the amdgpu firmware and now everything works. Conclusion: it's not a Guix issue, it's just that AMDGPU won't work without the proprie= tary blob. What a shame... The ATI driver works reasonably well with the RX580, but it is lacking in t= erms of X support. I noticed that beside failing to wake up from sleep, it also fails with many RandR queries (for instance `xrandr` would only list 2 mode= s out of 14 with my screen, brightness queries would fail with redshift, etc.). Does anyone know if ATI intends to improve support with the RX580? =2D-=20 Pierre Neidhardt https://ambrevar.xyz/ --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEUPM+LlsMPZAEJKvom9z0l6S7zH8FAlxa5q4ACgkQm9z0l6S7 zH9atAf+OMmteIXUxCbx7xOIOPLUCqR2xFxPSl7wsJrZNDSogzIQXR9jHwU6rfPE pnf+qXHrLrtRc4VN2xcPUxy+PdslDlMjsAJ1fizpxgVeDYtDjhCWN+9WVcXIwt1E lXthcPkAoJfQ9XI072785IxkyNteLrwRmu6OD4BVm6deReq+CJ2qeALHk+ntf5WL osXF7QkS6SIbendHsSX0rHJ747rpta4Z2z7TIAjXWO+26WEl3VmIucvIppKBXovf BWNNQ+OPLwsPZSFRX4Si0NzZ47T1Tnn/z9b42KItRC3n6Es2cKWsVjd/u+3IMb/G 9A/TOvokwgA7j2CmQXW8xkt7iM+icA== =oOvq -----END PGP SIGNATURE----- --=-=-=--
