您好，我是 Linux 新手，今天安装了 Kubuntu，现在我的笔记本电脑启动需要 10 秒左右，而使用 Windows 11 时则需要 1.5 秒。我能以某种方式解决这个问题吗？
另外值得一提的是，我觉得我的电脑启动了 2 次？msi 徽标出现了 2-3 次，然后才显示 kubuntu 界面。

答案1
10 秒的实际启动时间还不错。我看不出这是“问题”。如果您经常关闭和打开笔记本电脑，则可以使用暂停而不是关机。如果您不经常这样做，那么等待 10 秒并不算太长。
我的系统启动需要 12 秒，我不认为它“慢”。
Windows 启动速度实际上不会在 1.5 秒内完成。它使用的是快速启动，也就是休眠。如果你重新启动 Windows，你会发现它的启动速度比 Ubuntu 慢得多。
您还可以在 Ubuntu 中启用休眠或混合睡眠。但在某些硬件上，它可能无法正常工作。这就是为什么它默认被禁用的原因。
供应商徽标出现几次也是可以的。
