I have added some apps and programs to the desktop (since I'll be using them often), but then I found that I can actually pin my favorite programs to the launcher. So, now I don't want anything on the desktop to keep it neat and tidy. Unfortunately, when I tried moving the icons to the "trash" I deleted the actual programs/apps (so I undid my action). How can I solve this on Ubuntu 17.04? Thanks a lot.
Here's what I got from ls -a ~/Desktop:
org.gnome.Calendar.desktop
.. org.kde.kolourpaint.desktop
dell-driver-installer.desktop photocollage.desktop
eog.desktop simple-scan.desktop
gallery-app.desktop sol.desktop
gnome-mahjongg.desktop system-config-printer.desktop
org.gnome.Calculator.desktop unity-activity-log-manager-panel.desktop
