Description Yusoo 2017-11-24 23:04:16 UTC 
Description of problem:
SELinux is preventing plymouthd from 'map' accesses on the chr_file /dev/fb0.

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

If plymouthd는 디폴트로 fb0 chr_file에서 map 액세스를 허용해야 합니다. 
Then 이 버그를 보고해야 합니다. 
이러한 액세스를 허용하기 위해 로컬 정채 모듈을 생성할 수 있습니다. 
Do
allow this access for now by executing:
# ausearch -c 'plymouthd' --raw | audit2allow -M my-plymouthd
# semodule -X 300 -i my-plymouthd.pp

Comment 7 Marc Jadoul 2018-01-06 10:44:04 UTC 
Hello,
I have the same error. 
Actually I am using NVIDIA driver because Nouveau locked several time on my laptop. 
My laptop boot. Wayland is disabled in GSM config. After boot when I log in, my graphical interface freeze including the mouse . 
After reboot I can see this selinux error.... But there may be other errors.
Comment 8 Marc Jadoul 2018-01-06 10:45:47 UTC 
NB: I have the right selinux policy installed.
