Comment # 14 on bug 1189024 from Simon Lees

Ahh I forgot to hit save on my previous comment. By default on openSUSE
installs you should have a package branding-openSUSE installed, it should cause
*-branding-openSUSE packages to be preferred over *-branding-upstream packages.
Which at a guess is what is happening here.

There is also a package branding-upstream, which if installed will cause people
to prefer upstream branding everywhere (plymouth, lightdm etc as well as
desktops). As far as i'm aware nothing else is recommending *-branding-upstream
while the branding-openSUSE package is installed.

As a work around you can encourage people to either install branding-upstream
or "zypper in sway sway-branding-upstream". But i'm not really sure that
installing sway-branding-upstream when branding-openSUSE is installed is the
right thing to do I think this is the intended behavior in openSUSE.
