CorvusRuber As far as I remember they are enabled by default.....
Thanks ... I seem to remember that, too, but it's been a while. Apparently I have a different problem, then.
I assumed they were turned off by default because I created a VM in VirtualBox and tried to place a shortcut for it on the desktop. I've done that dozens of times, but this time it didn't work. This is the first time I've created a VM since I reinstalled Solus on this laptop, so I'm not sure what went wrong.
The background is set to "Folder View," apparently by default, as I haven't changed it.
