RDP stops working when screen locks / turns off Ubuntu 22.04

Refer: https://www.youtube.com/watch?v=63uppKZ_Alk

On PopOS 22.04 I installed the application with Firefox, it seems like newer versions of Ubuntu required me to use Chrome, instead.

sudo apt-get install chrome-gnome-shell

Skip password with sudo command

To execute the systemctl restart bluetooth command without entering a password on Ubuntu Linux 20.04, you can set up a specific sudoers configuration. This allows your user account to execute this specific command without being prompted for a password.

Follow these steps:

Open the sudoers file using the visudo command. It's essential to use visudo to edit the sudoers file to prevent syntax errors:

sudo visudo

Scroll down or navigate to the bottom of the file and add the following line:

your_username ALL=(ALL) NOPASSWD: /bin/systemctl restart bluetooth

Replace your_username with your actual username on the system. This line grants your user account permission to run the specified command without a password prompt.

Save the changes and close the editor. In visudo, you can save by pressing Ctrl + X, then Y to confirm changes, and Enter to exit.

Now, when you run sudo systemctl restart bluetooth with the specified username, it shouldn't prompt for a password. Remember to be cautious when modifying sudoers, as incorrect settings might impact system security. Always follow best practices and ensure you're aware of the security implications.
