我将内核升级到 4.4.8 版本，尝试启用挂起/休眠，但结果却缩短了电池寿命。因此我想
A. 在我的 Ubuntu 16.04 LTS 中删除 je 4.4.8 并恢复到 4.4.0 内核
b.保留新内核，但将旧内核（4.4.0）设为默认启动内核。
我对此有点缺乏经验，所以我希望了解步骤和提示：)
此外，我是否应该继续使用已发布的内核并等待系统的修复和更新，还是应该根据需要升级内核。有什么建议？

答案1
重新启动计算机，当 BIOS 完成后，快速按下shift以打开 GRUB 菜单，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*"
