After the first login after booting, the desktop takes about a minute or two to show up, and I can only see the mouse and the desktop background. No dock, programs, or applications. I am using a 7200 2tb Segate harddrive, a ryzen 5 1400, and a gtx 1060 3gb with NVIDIA drivers.
Same occurred with me, fresh install using elementaryos-0.4.1-stable.20180130.iso on a HP Pavilion with NVIDIA GForce 1050 and integrated Intell Graphics.
The way I resolved this is when the login screen appears instead of typing the password I have pressed Ctrl+Alt+F1 (F2,F3..F6 will also work), login from console (username, enter, password, enter) and then I have typed
sudo apt update sudo apt upgrade sudo ubuntu-drivers autoinstall
The last line helps sp intel microcode and NVIDIA drivers was also installed. Force shutdown by holding a few seconds the Power Off button (
sudo reboot now freezes with a lot of nouveau error messages) and once the system has started again I was able to login into the desktop.
