SELinux is preventing /usr/libexec/gnome-session-check-accelerated-helper from read, write access on the chr_file nvidiactl.

*****  Plugin device (91.4 confidence) suggests  *****************************

If you want to allow gnome-session-check-accelerated-helper to have read write access on the nvidiactl chr_file
Then you need to change the label on nvidiactl to a type of a similar device.
# semanage fcontext -a -t SIMILAR_TYPE 'nvidiactl'
# restorecon -v 'nvidiactl'

*****  Plugin catchall (9.59 confidence) suggests  ***************************

If you believe that gnome-session-check-accelerated-helper should be allowed read write access on the nvidiactl chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep gnome-session-c /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Hash: gnome-session-c,xdm_t,device_t,chr_file,read,write


#============= xdm_t ==============
allow xdm_t device_t:chr_file { read write };

audit2allow -R

#============= xdm_t ==============
allow xdm_t device_t:chr_file { read write };

Just curious: Could this cause a blank screen after waking from suspend/hibernate?
