无法在非戴尔系统上运行

use*_*159 5 dell asus 18.04

我在Asus X550V上安装了Ubuntu 18.04,从官网下载。安装过程一切顺利,没有任何错误。启动 Ubuntu 后,我更新了它,然后重新启动了电脑。当它启动时,它挂在启动屏幕上并出现以下错误:Unable to run on non-Dell system
我再次重新启动它并在grub上打开Ubuntu 的高级选项,然后我选择在旧内核上启动(我的 PC 中的最新内核是)。PC 启动没有任何错误。 但是当我运行时,我遇到了以下错误: 4.15.0-20-generic4.15.0-23-generic

在华硕 PC 上出现有关戴尔的错误似乎很奇怪。
对此有什么解释和解决办法吗?

PS:PC配备Nvidia GTX 950M显卡。
