Description of problem:
nVidia VGA Driver instalation
SELinux is preventing sddm-greeter from 'map' accesses on the chr_file /dev/nvidiactl.

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

If you believe that sddm-greeter should be allowed map access on the nvidiactl chr_file by default.
Then você deve informar que este é um erro.
Você pode gerar um módulo de política local para permitir este acesso.
Do
allow this access for now by executing:
# ausearch -c 'sddm-greeter' --raw | audit2allow -M my-sddmgreeter
# semodule -X 300 -i my-sddmgreeter.pp
