In previous Ubuntu releases, the user was able to modify the Unity wallpaper in the System Settings programme (Appearance panel). This action no longer has an effect on Ubuntu 18.04.

How can I change the Unity wallpaper in this Ubuntu release?

Update I: this is the output requested by Joshua Besneatte:

$ pstree -s $(pidof X)|grep gdm
        |      |                 |                 `-2*[{gdm-wayland-ses}]
        |      |                 `-2*[{gdm-session-wor}]
        |      |-gdm-session-wor-+-gdm-x-session-+-Xorg---3*[{Xorg}]
        |      |                 |               `-2*[{gdm-x-session}]
        |      |                 `-2*[{gdm-session-wor}]
        |      `-2*[{gdm3}]

Update II: following some discussions on Google+ I tried disabling Wayland. This had no effect, though.

    Have you installed and logged into Unity manually (18.04 has GNOME by default)? – pomsky Aug 17 '18 at 8:23
  • Unity was installed automatically. – Luís de Sousa Aug 17 '18 at 8:28
  • it should be gdm... what happens if you run this pstree -s $(pidof X)|grep gdm – Joshua Besneatte Aug 17 '18 at 8:31
