I recently tried setting up an Intel NUC for remote access but it required a display to be connected -- I am using Ubuntu 18.04 (maybe 20.04, I can't check). So I installed the X11 dummy driver according to this: https://help.realvnc.com/hc/en-us/articles/360005081572-Display-issues-when-connecting-to-VNC-Server-running-on-Linux, but the NUC isn't attached to wifi/internet and I can't view via a monitor now to change it. How can I edit the /etc/X11/xorg.conf file or reset the settings?
Thanks... happy to share more information if needed
