I have installed Loki on my brand new Gigabyte Sabre 17, replacing windows 10 completely. It boots, I log in to either my own account or the guest account, the wallpaper comes up and then ... nothing, No taskbar, no dock. CTL-ALT-Fx does not get me to a TTY and after a while the mouse cursor disappears too. Any ideas? Update: I got it working by going into the BIOS and disabling everything in sight. Would be nice to know just what the problem was, though.
