Description of problem:
SELinux is preventing bumblebeed from 'execute' accesses on the file /usr/bin/Xorg.

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

If 您确定应默认允许 bumblebeed execute 访问 Xorg file。
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 bumblebeed /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
