Hi,

Not running nitrogen.
Getting this error when run QuickWall without any parameters:

Hey @G-R-A-F-F Can you try passing the flag --setter xfce. It should work that way. By default it tries to use nitrogen which in your case won't be installed.

$ QuickWall --setter xfce

gleba, It looks like you are missing Imagemagic install.
