Description of problem:
SELinux is preventing ps from 'search' accesses on the diretório lightdm.

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

Se você acredita nisso ps deve ser permitido search acesso no lightdm directory por padrão.
Then você deve informar que este é um erro.
Você pode gerar um módulo de política local para permitir este acesso.
Do
permitir este acesso por agora executando: # ausearch -c 'ps'--raw | audit2allow -M my-ps # semodule -X 300 -i my-ps.pp
