Created attachment 455470 [details] ebuild Xfwm4 can work as a standalone window manager without most of the Xfce. However, by default, it doesn't consider root pixmap (wallpaper), thus displaying gray background if xfdesktop is not running. But this option can be switched on with -DMONITOR_ROOT_PIXMAP=1, allowing you to have wallpaper of your selection, set for example with feh. In attachmant you can find my ebuild where I've added "rootpixmap" USE flag and function src_compile. src_compile() { if use rootpixmap; then emake CFLAGS="${CFLAGS} -DMONITOR_ROOT_PIXMAP=1" || die else emake CFLAGS="${CFLAGS}" || die fi }
