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
