@rolf, are you using legacy boot or uefi? NVIDIA? If NVIDIA, you may need to manually set a console resolution that matches the native monitor resolution. For example, "set gfxpayload=1920×1080" in grub.cfg which works around oddities in the nvidia xorg driver. If it's Intel graphics KMS should be handling this automatically and your best bet is to file a bug report at the freedesktop
bug tracker.
@Joe, yes networkmanager works perfectly now. I only used systemd-network when I was on Linux because it was easy to configure and I wasn't using a frontend. I had a very "crafted" installation.
