SELinux is preventing /usr/sbin/lightdm from 'create' accesses on the file .xsession-errors.

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

If vous pensez que lightdm devrait être autorisé à accéder create sur .xsession-errors file 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 lightdm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
