I'm relatively new to Linux, have been using it for about 6 months already. I like Gnome shell more than Unity but looks like in 16.04 Ubuntu plays a trick on me. As soon as I install gnome Ubuntu gets stuck on loading.
Basically I did the following:
sudo apt install gnome-shell
Installation process is done and then I do:
Regardless if I do the
sudo apt update && sudo apt upgrade -y
First it still ends up with the same result. Also it does not matter if I really switch to gnome or not before I do reboot. The only thing I can do after installing gnome and rebooting is basically booting with GRUB and logging into the system via safe mode and removing the gnome shell. As soon as done the system loads perfectly fine as it's supposed to.
Anyway this has not been a problem for me in the 14.04 at all and I was unable to google any good solutions so far.
I run Ubuntu on Dell Inspiron 5558 laptop, if that's of any help at all. And also I do use proprietary Nvidia drivers (361.42) instead of default nuoveau drivers.
