Description of problem:
I've tried to mirror nvidia virtual display and my monitor
SELinux is preventing gdb from 'read' accesses on the chr_file nvidiactl.

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

If you believe that gdb should be allowed read 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.
Do
allow this access for now by executing:
# ausearch -c 'gdb' --raw | audit2allow -M my-gdb
# semodule -X 300 -i my-gdb.pp
