Ubuntu Gnome 15.10 hangs at splash screen, loading icon freezes

So I've recently installed ubuntu gnome 15.10 on my HP laptop and at first it all runs fine I have all my apps installed that I want but when I reboot it stops at the loading icon and freezes. I've had the problem before but I reinstalled Ubuntu but now its back again, the last few times it happened I could unfreeze the icon by pressing the power button on my laptop, it would begin moving again but would my laptop would shutdown, this no longer happens so I have to kill my laptop to turn it off. I've just booted in like usual from grub and held down shift to see what happens when it freezes and it stops at this point:

[OK] Started User Manager for UID 1000.

Its been at this point for several minutes now. I've tried searching for people with the same problem but their fixes didn't work for me.

Solution 1:

I've recently had this problem with Ubuntu 15.10. I installed gnome-shell from the Software Centre and after rebooting it froze on bootup. Looking in syslog I saw the exact same message:

[OK] Started User Manager for UID 1000.

After searching around, I found this: gdm not working with Ubuntu 15.10

Installing ubuntu-gnome-desktop, then running dpkg-reconfigure gdm fixed the problem for me.
