Recently I switched from Xubuntu to Debian, particularly Debian 9.1 xfce. My system in up to date however, I am not able to change the wallpaper using the GUI options. When I opt RightClick > Desktop Settings , the pop up shows the wallpapers and I am able to change it but when I try to choose a custom folder its all greyed out, so I am not able to choose a custom folder say "Pictures" or "Downloads" folders. I haven't tried any cmd lines to change my background yet since I don't wanna change it like so but I would like to know why its so ? How I can solve it out ?
I am not able to browse any of the folders other than the default directory, and ofcourse the default current dir /usr/share/images/desktop-base - I can't select that even, since its greyed out too. However its showing the default wallpaper of Debian 9.1.
I installed this from the DVD official download as normal. This user doesnt had any sudo permission at the time of install, lately added sudo permission using the command
