Ubuntu 18.04 freezes after login [closed]

Question

Yesterday I installed Ubunted on my laptop (Dell XPS 15 9560) and the installation went fine. I plugged in the USB and created an ext4 partition, made a user with a password and everything.

Then I boot up Ubuntu, it takes me to the log in screen, I type my password, and then all the UI except the mouse (which is frozen) disappears and nothing happens.

I have tried reinstalling the desktop with sudo apt-get install --reinstall ubuntu-desktop and udating the Intel graphics driver, both of which didn't help

(this is my first time asking a question here, so please go easy on me)

Answer 1

I got it working on my own. It was throwing this error:

NMI watchdog: Watchdog detected hard LOCKUP on cpu 2

watchdog: BUG: soft lockup - CPU#* stuck for 22s!

I followed this video: https://www.youtube.com/watch?v=nPprHes-K_Y and it solved my problem.

EDIT:

The video describes editing the grub configs. You can either do this by pressing 'e' while in grub menu or by dropping into recovery mode and editing the /etc/default/grub file:

To the GRUB_CMDLINE_LINUX_DEFAULT, add nouveau.modeset=0
