Hi team.
We have successfully done with the initial bring-up of the gnome on ubuntu-22.04
When we are trying to launch the gnome using gdm3 upon login the gnome desktop launches we see a blue screen until the configured wallpaper is set.
We found that, once we set the wallpaper from the user through settings->Background then it changes to newly set wallpaper and after reboot, the wallpaper appears upon login and no blue screen is seen.
Our goal is to set the wallpaper at the rootfs build time itself so that once the login is done we should just see the configured wallpaper instead of getting the blue screen for 2-3 seconds and then get the configured wallpaper.
We tried changing the dconf settings:
mkdir -p /etc/dconf/profile
echo -e "user-db:user\nsystem-db:local" > /etc/dconf/profile/user
mkdir -p /etc/dconf/db/local.d
cat > /etc/dconf/db/local.d/01-background << 'EOF'
[org/gnome/desktop/background]
color-shading-type='solid'
picture-opacity=100
picture-options='zoom'
picture-uri='file:///usr/share/backgrounds/default_wallper.jpg'
primary-color='#023c88'
secondary-color='#5789ca'
show-desktop-icons=true
EOF
chroot ./rootfs dconf update
But in this case also it did not work, after the login we see the same blue screen for 2-3 seconds after which the configured wallpaper is set.
Screenshots has been attached for your reference.
