我在 Acer Swift 上安装了 Lubuntu - 将其安装在 SSD 上已经需要将控制器的 BIOS 设置更改为 AHCI。
现在我被困在如何让关机正常工作上。我已经尝试了一些选项，/etc/default/grub比如
reboot=biosacpi=force apm=power_offpci=nomsi,noaer（我知道这只能关闭错误信息）
我关机时遇到的错误是：
PCIe Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, (Requester ID)
device [10de:id13] error status/mask=00100000/00000000
[20] UnsupReq (First)
TLP Header: 40000008 000000ff a024c010 f7f7f7f7
显示该错误后，什么也没有发生，并且无法正常关闭。
我还没有安装额外的 SATA——我想在修复关机后安装它......

到目前为止，我看到的有关此类错误的问题大多数情况下都是“严重性=已纠正”或其他“类型”。如果您需要更多信息，请发表评论，我会更新问题。
我现在怎样才能让它正常关闭？

答案1
我现在解决了这个问题，为了不让问题得不到回答，我只能自己回答我自己的问题。
我现在做的事情：
- 将显卡驱动程序设置为 nvidia-driver-435
- 通过 synaptic 包管理器更新所有需要更新的内容
现在它就顺利关闭了。
