To remove a desktop item (In the process of replacing nautilus with an older version, a "Computer" icon appeared on the desktop), I used dconf-editor
to toggle the entry show-desktop-icons
in org.gnome.desktop.background
.
This worked, but after a reboot, the background (previously a picture) does not show. Instead: a black screen is shown.
Reading the configuration in dconf, the values set are:
color-shading-type: solid
draw-background: true
picture-opacity: 100
picture-options: zoom
picture-uri: file:///usr/share/backgrounds/Last_breath%E2%80%A6_by_Francisco_Javier_Epinoza_P%C3%A9rez.jpg
primary-color: #000000
secondary-color: #000000
show-desktop-icons: false
I've checked the location of the file: it exists as expected.
System Settings > Appearance also reports this background.
How to re-enable the background image?
