Description of problem:
SELinux is preventing /usr/bin/Xorg from 'setopt' accesses on the netlink_kobject_uevent_socket .

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

If 您确定应默认允许 Xorg setopt 访问  netlink_kobject_uevent_socket。
Then 您应该将这个情况作为 bug 报告。
您可以生成本地策略模块允许这个访问。
Do
请执行以下命令此时允许这个访问：
# grep Xorg /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
