Most things will work out-of-the-box, or just follow the normal set-up method. However, there are some issues you may want to solve before or during installation.
Keyboard not functioning properly
The keyboard may not function correctly, esp. normal input will not work. The behaviour includes: 1. keyboard light not switchable; 2. only some functional hotkeys are functioning. The issue may disappear after some time (varies from a few seconds to tens of minutes), or maybe not.
One way to workaround this is to add a kernel parameter during booting:
This is due to Panel Self Refresh (a power saving feature of Intel iGPUs). See Intel graphics#Screen flickering for more information.
The current recommend way is to disable it, by adding with this extra kernel parameter:
WiFi interface missing
The WiFi interface is missing sometimes after rebooting from Windows, but
rfkill can still discover it.
It is known that after powering-off and booting again, this will be corrected.
Audio not working
Touch screen and pen not working
Update kernel to version >= 5.10.15
