记录ubuntu的安装过程。

优化apt

登录时使用Ubuntu on X11 Org，否则Theme不能切换。因为Gnome Wayland不成熟。

Recommend: Software & Update->Download from->Other去选择aliyun镜像。

通过上面的设置，已经实现了连接到 ZeroTier 的设备使用内网 IP 访问局域网，但是局域网内的设备仍然无法使用 ZeroTier 分配的 IP 来访问那些连接到 ZeroTier 的设备，我们还需要在路由器中配置静态路由:

内部网络--->路由设置：

网络 / 主机 IP: 与 ZeroTier 网段保持一致： 192.168.195.0
网络掩码: 与 ZeroTier 掩码保持一致 (/24 为 255.255.255.0)： 255.255.255.0
网关: 安装 ZeroTier 设备的内网 IP： 192.168.3.2

TouchPad Driver

Thinkbook 16+ 2025需先升级ubuntu到24.10及以上版本，参考：

https://www.bilibili.com/opus/1085833462664921088

1.获取本机硬件ID (DMI Modalias)

1
cat /sys/class/dmi/id/modalias

2.创建配置目录和文件

1
2
sudo mkdir -p /etc/libinput/
sudo vim /etc/libinput/local-overrides.quirks

3.写入、修改并保存配置
