Comment # 3 on bug 938955 from Martin Vidner

I have made two installations of
openSUSE-Tumbleweed-DVD-x86_64-Snapshot20150802-Media.iso, with default
settings, one without the recommended packages.

(unfortunately a problem with bugzilla prevents me from attaching the logs; see
https://w3.suse.de/~mvidner/y2logs-kde.tgz
https://w3.suse.de/~mvidner/y2logs-kde-norec.tgz 1MB in total)

Indeed without the recommended packages no GUI comes up. I have been able to
fix that by:
- changing the systemd default.target from multi-user.target to
graphical.target
- zypper in --no-recommends sddm xinit xorg-x11-server xorg-x11-driver-input
xdm
