If the translator is correct (please use English):
Ubuntu, and thus Lubuntu, don’t have root enabled by default. If you want to use root, you just need to give root a password.
sudo passwd root
Then enter a password twice and you can then use the root account.
At present, using QT to do a project, you need to boot directly into the root authority, and use the serial port resources
Lubuntu20.04 how to complete root account login in one step without password
Project development needs requirements like this
- Enabling the
rootpassword is the wrong way. It does not solve your problems, but makes your whole system less secure. (I am missing a dislike-button)
- You don’t need to be
rootto access serial ports. Serial ports are owned by

dialout. Adding your user to the
dialoutgroup is the recommended way.
- Login as
rootand run a graphical environment is completely wrong.
- This is a forum, not a chat. There is absolutely no need to post line by line.
I also agree enabling
root is a bad idea. More information here:
