Hi all. Well aware of the forum rules, but I can't log into my Kali box to screenshot or copy output.

I am running Kali 2016.1 on my laptop. On a fresh install, I make sure to apt-get update / upgrade / dist-upgrade

Once completed, I run the linux-headers-$(uname -r) for the new linux headers

When I'm done with all that I go for the next command on the Kali instructions on the website, which needs me to install the nvidia-kernel-dkms and then

sed 's/quiet/quiet nouveau.modeset=0/g' -i /etc/default/grub
update-grub
reboot

Here is where the issue pops up. It won't log me into the GUI - it just comes up with a screen that says "Oops, something went wrong and the system couldn't recover".

For the life of me, I can't figure out why this is happening. Reaching out for some advice and thank you in advance for taking the time to read the post.
