如何删除新内核并使旧内核成为默认值 (16.04)

Question

我将内核升级到 4.4.8 版以尝试启用挂起/休眠，但反过来又缩短了电池寿命。所以我想要么

一个。在我的 Ubuntu 16.04 LTS 中删除 je 4.4.8 并恢复到 4.4.0 内核

湾 保留新内核，但使用较旧的 (4.4.0) 默认引导内核。

我对此有点缺乏经验，所以我想要步骤和提示:)

另外，我应该坚持使用随附的内核并等待系统的修复和更新，还是应该按照我认为合适的方式升级内核。建议是什么？

重新启动您的计算机，当您的 BIOS 通过快速按下shift打开 GRUB 菜单时，您可能需要尝试几次才能获得正确的时间。

选择高级选项并选择使用旧内核启动。然后您可以安全地卸载属于较新内核的所有内容并完成它：

sudo apt-get remove "linux-headers-4.4.8*"
sudo apt-get remove "linux-image-4.4.8*"
