我在戴尔 Inspiron 3542 上使用 Ubuntu 22.04.1 LTS,使用 4GB RAM 和 NVD7。每次启动操作系统都需要 1 到 5 分钟以上(不使用任何双启动)。
以下是systemd-analyze
Startup finished in 4.336s (kernel) + 1min 24.904s (userspace) = 1min 29.241s

我也面临笔记本电脑风扇问题不会关闭即使在系统完全关闭后(该问题也出现在所有 Linux 发行版中(尝试过 Fedora 并遇到同样的问题)但在 Windows 中它运行良好。
我是 Linux 新手,非常感激任何帮助。

有几件事你可以做来减少这段时间:
- 停用普利茅斯启动屏幕
- 打开终端,输入
sudo gedit /etc/default/grub
并按回车键。 - 查找
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
(或类似这样的)行并将其更改为GRUB_CMDLINE_LINUX_DEFAULT="fsck.mode=skip quiet"
。 - 保存并关闭文件。然后输入
sudo update-grub
并按回车键。
- 显然,Snap 正在“杀死”你。除非你是它们的粉丝,否则我建议摆脱它们,改用 Flatpaks:
要删除 snap,您可以打开终端并输入:
sudo apt purge -y snapd && rm -rf ~/snap && sudo rm -rf /snap && sudo rm -rf /var/snap && sudo rm -rf /var/lib/snapd && sudo apt-mark hold snap
。请注意,这将删除您的 Mozilla Firefox,因为它是一个 snap。为了在 ubuntu 上使用 flatpaks,只需在终端中输入
sudo apt install -y flatpak && flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
,然后,您可以通过输入来安装 Firefoxflatpak install -y flathub org.mozilla.firefox
。 您可能需要重新启动才能使用它。此外,由于快照已消失,您需要通过键入来安装 gnome 软件和 flatplak 插件
sudo apt install -y gnome-software gnome-software-plugin-flatpak
。
- 您还可以做另一个小改进,即避免在初始化时等待计算机上线。这可以通过
sudo systemctl disable NetworkManager-wait-online.service
在终端中输入并按回车键来实现。
与现在相比,这三项调整将大大减少您的启动时间。
希望对您有帮助:)
