Description of problem:
SELinux is preventing /usr/libexec/gnome-settings-daemon from 'write' accesses on the directory /dev/shm.

*****  Plugin catchall (100. confidence) suggests   **************************

If vous pensez que gnome-settings-daemon devrait être autorisé à accéder write sur shm directory par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
autoriser cet accès pour le moment en exécutant :
# grep gnome-settings- /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
