Something is fundamentally not working here. I'm just trying to change the
desktop background picture.
I go into Settings > Desktop. The "Background" tab is open by default.
The "Folder" dropdown list offers several predefined locations. I pick
"Other", and a file selection dialog opens, showing the contents of
"/usr/share".
But every file and subdirectory of "/usr/share" is grayed out and disabled.
I can't actually browse the filesystem. The dialog is dead.
The only thing I can do here is pick from one of the preselected directory
locations on the left, like "Desktop", "Documents", "Music",
etc. Each one
opens the corresponding directory, but that's it. Every file and
subdirectory is grayed out and disabled.
I'm seeing this on two separate laptops that were upgraded to F26. What the
heck is going on?
