I am unable to change the GDM3.8 login wallpaper.
I tried updating the wallpaper with sudo gdm3setup.py.
Also changing org.gnome.desktop.background with dconf-editor changes only the background of gnome-shell not the login screen from GDM.
I am only seeing a grey background, whatever I do.
How should I update the GDM3.8 login wallpaper?

To change the wallpaper of the login screen use
# mkdir /opt/login
# echo -e "[org/gnome/desktop/background]\npicture-uri='file:///opt/login/wallpaper.jpg'" > /etc/dconf/db/gdm.d/01-background
# cp [YOUR FILE] /opt/login/wallpaper.jpg
# dconf update
where [YOUR FILE] needs to be a *.jpg picture.

It does not seem to work. The contents of /etc/dconf/db/gdm.d/01-background is now
[org/gnome/desktop/background]
picture-uri='file:///opt/login/wallpaper.jpg'
Also I checked that the image can be viewed.
But still the wallpaper does not show in GDM.
*edit: I am using a theme in GDM, I dont know if this matters?

Yes that is what it looks like. I find it rather weird that I have to go to so much trouble in order to change the GDM wallpaper. In GDM 3.6 I could just start up gdm3setup and select a different one.

Well this is supposed to be the overlay for the wallpaper. Much like in the lock screen. This is not a bug, but a feature.

I haven't tried yet with Gnome 3.8, but on Gnome 3.6, just before the update, I noticed a few things. First, gdm3setup would let me choose a wallpaper for gdm, but it only seems to apply it to the lock screen. There is a file in a gdm folder, I believe it was in /usr/share/* somewhere (I'm not at my Arch box presently) named texture.png or something to that effect and if you move a background pic to that folder, properly sized and converted to the same format and renamed to what the original was, then you could get it to work that way. I think I also got it to work by editing a line or 2 in one the configuration files there and pointing it to the picture I wanted. When I'm at my machine, I'll try this again and see what I actually had to do and if it works now with 3.8.

This is the file, just make sure the resolution is correct for your screen.
/usr/share/gnome-shell/theme/noise-texture.png

This ended up being my solution, after every other documentation/solution proved unfruitful with GDM 3.12.
Should we be updating the GDM wiki entry to address this, or is the offered solution still relevant despite not working for us?
