I use feh to set fixed background (wallpaper) in X (one line in .xinitrc):feh  --bg-fill --no-fehbg some_image_file &Is this possible to remove background using feh (or any other tool/command) during X session?I know that I can use some kind of dummy image like black.png but I'd rather prefer not creating additional file for such a simple task.
remove background with feh?
x11;wallpaper;feh
xsetroot allows you to specify greyscale or solid colour backgrounds.
