For Nomachine installed on a server, how do I increase the resolution?

Question

The resolution is stuck at roughly 1000x700. Neither display settings nor xrandr + cvt let me adjust the available display sizes. How do I increase the resolution?

Answer 1

Edit/create /etc/X11/xorg.conf to contain the following:

Section "Screen"
    Identifier "MyScreen"
    Subsection "Display"
        Virtual 1920 1080
    EndSubSection
EndSection

(In the above case for a resolution of 1920x1080)
