--- Comment #13 from Lamarque V. Souza <lamar...@kde.org> --- Since you do not have the host command installed, the output of the second command is useless. Can you ping your hostname? Like this: $ ping -c 1 Juan-PC NetworkManager does not directly change computer's hostname. The dhcp client does. Let's first try to understand what is causing your problem before messing with xauth and DISPLAY. What is you Linux distribution? I need you to send me NetworkManager's log and the way to retrieve it depends on which distribution you use. If you use one that uses journald you can retrieve it running the following command as root: journalctl -u NetworkManager.service -- You are receiving this mail because: You are watching all bug changes.
