That explains everything. It’s almost like an dead end, but now at least everyone who has seen the solid grey color - will know why that is so and I’m here wondering “how’d you even find info on this stuff!?”
I’m using 99.90% AL defaults for my configs, so the default compositor is called Picom (for Xfce4 install)
# start the compositor (transparency, fade, shadows, blur, etc.)
picom -b &
Yep I disabled it, just to see if the grey is gone. The grey is gone, and now I have pure void of blackness instead of the grey XD doesn’t sound like a fair tradeoff to me to disable the compositor so I that don’t see the grey.
The reason I kept seeing the AL branded WP of mountains (between my newly found colorful/cheerful plasma bgs) was because of this:
# restore the last wallpaper applied with nitrogen
nitrogen --restore &
So if you find yourself annoyed you gotta check here:
I tested it, and I couldn’t get this config to work:
## And this example didn't work either:
But this one works, gotta create an new folder in /usr/share/backgrounds and place your “1-2 second dummy background” in that folder:
There is still 1 tiny compositor side effect, it blinks (but with the right background this time) but it is what it is, you can disable compositor to get rid of this blink. But if you know why it is happening, it might not be an issue for you any longer xD
Thank you @PackRat for finding the root of this issue feeling in peace!
