As the title said, on Wayland, you can use GUI app as root by typing its name in the terminal follow by admin:///. For instance, I run Nautilus as root by:
nautilus admin:///
Normally, I should get Nautilus window open and able to edit files in root directory. However, Nautilus opens with a message showing that I don’t have permission to access the requested location.
Please help, I updated Tumbleweed to the latest version. Thanks.
nautilus admin:///
