我在新款联想 Carbon X1 2018 上的 ubuntu 17.10 和 ubuntu 18.04 上设置 Virtualbox 时遇到了多个问题。首先是 CPU 节流问题，我尝试使用 archlinux 中的修复程序来解决这个问题https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X1_Carbon_(Gen_6)#Temporary_fix
现在我在修复此问题时遇到了另一个问题：

有谁修复过这个问题吗？
答案1
Arch Wiki 有误。您需要删除 *.timer 文件中的“Requires”行，并删除 *.service 中的“[Timer]”部分。
我已经更新了 Arch Wiki 来反映这一点。
