昨天我安装了Bumblebee-nvidia，但是我收到的警告很少，如下所示：
update-initramfs: Generating /boot/initrd.img-4.15.0-23-generic
/sbin/ldconfig.real: Warning: ignoring configuration file that cannot be
opened: /etc/ld.so.conf.d/i386-linux-gnu_EGL.conf: No such file or directory
/sbin/ldconfig.real: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf.d/i386-linux-gnu_GL.conf: No such file or directory
/sbin/ldconfig.real: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf.d/x86_64-linux-gnu_EGL.conf: No such file or directory
/sbin/ldconfig.real: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf: No such file or directory
我必须担心这些警告吗？如果是，那么如何解决？
