Board $> cat /etc/default/weston

Please comment the content of the file /etc/default/weston or delete it.

Board $> systemctl stop Weston@root.service

Please remove the capital letter in the word Weston. The correct command is

Board $> systemctl restart weston@root.service
Board $> systemctl stop weston

Please use the full Weston service name "weston@root.service". The correct command is

Board $> systemctl stop weston@root.service

Note: You can list all systemctl services with the command

Board $> systemctl list-units
