• displaymanager-awesome-20151221.png looks like first_boot-displaymanager-20151221.png looks like https://openqa.opensuse.org/tests/105705/modules/first_boot/steps/1 . why are the two new images necessary? Probably it is me not knowing openQA enough
• why the "generic" name for x11_login-generic-desktop-20151221.json ?

x11_login-generic-desktop-20151221 deserves a workaround property btw as the bulb is clearly misrendered. And it should not be used for other desktops, i.e. it needs to be tagged as DESKTOP-awesom

why doesn't the background resemble https://github.com/madanyang/awesome-branding-opensuse/blob/master/themes/openSUSE/background.jpg ?

#53 to replace this PR:

• tag "ENV-DESKTOP-awesome" updated
• redundant needle deleted
• updated screenshot with Tumbleweed background: Does not matter for the test but does not confuse with distorted light bulb
