Ubuntu Laptop Setting

Windows-Linux 双启动设置中显示时间错误的问题

让 Linux 将硬件时钟作为本地时间

timedatectl set-local-rtc 1

你会看到一个关于 RTC 不使用本地时间的警告。对于桌面设置，它不应该引起任何问题。

Linux 高级电源管理 Laptop

TLP - Linux 高级电源管理 是一个小巧的命令行工具，它通过对 Linux 系统执行一些调整来真正帮助延长电池的使用寿命。

sudo apt install tlp tlp-rdw

配置文件中有很多选项，要启用某个选项的话只需要删除行首的 # 就行了。每个选项能够赋予什么值都有说明。下面是你可能会用到的选项：

• 自动休眠 USB 设备
• 设定启动时启用/禁用无线设备
• 降低硬盘转速
• 关闭无线设备
• 设置 CPU 以性能优先还是节能优先

ThinkPads only: External Kernel Modules

As of version 5.17, the Linux kernel in combination with TLP 1.5 offers full battery care support (i.e. charge thresholds and recalibration) for ThinkPads from model year 2011 onwards. Therefore no external kernel modules are required with kernel 5.17 or newer and you do not need to proceed any further here.

The output of tlp-stat -b will guide you which package to install:

• acpi-call-dkms (PPA or universe) – optional – External kernel module providing battery recalibration for ThinkPads since model year 2011 - e.g. T420/X220 and newer

• tp-smapi-dkms (universe) – optional – External kernel module providing battery charge thresholds and recalibration for ThinkPads before model year 2011 as well as specific tlp-stat -b output until model year 2011

Install the appropriate package either with your favorite package manager or the command

sudo apt install acpi-call-dkms
