In order to get 1440×900 I have first to stop the desktop manager and restart nx server, which is a little bit tricky to do every time. Don’t you have a better solution for this? Thanks October 2, 2019 at 14:13 #23856 fra81Moderator Hi, you can disable the desktop manager permanently: systemctl stop display-manager systemctl disable display-manager Alternatively you can use a HDMI Dummy Plug adapter.
