Hello Guix,

This fixes bug #37380 for SDDM users.

Today I was setting up my system following [0] to use realtime

scheduling with JACK and SuperCollider. After a lot of failures and a

lot of help on IRC from rekado I found out that it wasn't me it was just

a bug.

The bug is the same as [1] and my solution is the same as [2] but for

SDDM. I tested my patch with the attached system configuration

(shamelessly copied from [3]).

Thanks,

Giacomo
