Hello,
I have been using sys-gui for quite some time now. I got it working with the salt formula, but later made a minimal fedora template for it. I also made sys-gui disposable, based on a sys-gui-dvm. (The desktop environment is xfce4.)
Everything has been working fine, but the background image. When I try to change it from the xfce settings, it errors:
This was also a problem when I was using the sys-gui from the stock salt formula, and also before I made sys-gui disposable.
This may or may not be related to QubesOS, but I never rised my gui much, so I am unfamiliar with xfce4 bugs.
Any help is much appreciated.
