Comment # 14 on bug 1204657 from Milachew

I tried to download fresh ISO of 15.5.
Than, I ticked Generic Desktop system role.
And ticked GNOME Basic pattern.

After installation, Leap logo in GNOME Settings is present (but temporary its
very small, fixing of it in 41.7 version of gnome-control-center, which will be
in Leap 15.5 later).

Thanks everyone, this is fixed!
