I had a freshly installed Ubuntu 16.01.1 with same issues (thin fonts). The issue appeared with auto login only. Now I defined a auto-login-delay of 1 second and it works fine. To define the delay open the file "/etc/lightdm/lightdm.conf" and edit the line "autologin-user-timeout=1".
$ sudo nano /etc/lightdm/lightdm.conf autologin-user-timeout=1 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1506704 Title: Thin font, nautilus doesn't integrate with Unity.
