Basically, all machine functions working well, including:

• Intel AX200 wireless card
• HDMI output with audio
• DP output on USB-C port (one cable, including power supply, video and audio output)

Requirements

1. press enter on the Lenovo screen when booted.
2. press F12 enter the boot source selection screen.
3. chose your USB drive

third-party driver:

The opensource third-party driver for AMD Ryzen 7 PRO series chips runs really well on Thinkpad T14s, remember check the box on install wizard.

Optimization

Below sections are optional optimizations for Ubuntu. Make your own choice.

Tips: If you install Ubuntu with the latest ISO image from Ubuntu official website, you don’t need install the OEM kernel manully. switch to Linux oem kernel.

switch to Linux oem kernel

After you install Ubuntu, default kernel is generic. It may have some annoying problems, like, you can not size brightness with hotkeys, and display colors are not accurate compare to windows. Recommend switch to Linux oem kernel, all above problems will gone.

more details about OEM Kernels, see below link:

OEM Kernel

use this command to install:

sudo apt install linux-oem-20.04b

set mouse wheel speed

Ubuntu default mouse speed is too slow.We need use a config to make it better.

1. install imwheel

   sudo apt install imwheel
   

2. create .imwheelrc

   sudo gedit ~/.imwheelrc
   

   content:

   ".*"
   None,      Up,   Button4, 3
   None,      Down, Button5, 3
   Control_L, Up,   Control_L|Button4
   Control_L, Down, Control_L|Button5
   Shift_L,   Up,   Shift_L|Button4
   Shift_L,   Down, Shift_L|Button5
   

   change the number 3 more smaller if you think the speed is too fast.

3. starting onboot

   use command imwheel -kill to start imwheel. Also, you could use gnome-session-properties set this command as a startup command.

Change Ubuntu notification position to right

1. install gnome tweaks and gnome-shell-extensions

   sudo apt install gnome-tweaks gnome-shell-extensions
   

2. install Host Connector ()

   sudo apt install chrome-gnome-shell
   

3. use chrome open https://extensions.gnome.org/, install Notification Banner Position

Show the net speed on the status bar

1. make sure you already installed gnome-tweak, gnome-shell-extensions
2. search Net speed Simplified in the extensions store.

Software recommendation

For using Ubuntu more conveniently , I recommend some nice software on Ubuntu.

Onedrive

If you just migrate from Windows, and still have some important files on onedrive, you should use this opensource onedrive client for Ubuntu(works in terminal).

you can use the install script from github, or install from a custom apt repository.

1. add repository and install

   sudo add-apt-repository ppa:yann1ck/onedrive && sudo apt install -y onedrive
   

2. login

   onedrive
   

3. sync with specific directory

   onedrive --synchronize --single-directory [dirName]
