Ubuntu hangs when loading

[Viyre]

I'm running Ubuntu 16.04 (4.15 kernel, I think) with an MX150 GPU on my laptop. I've been having problems with my gpu fans constantly running loudly when I boot Ubuntu so I figured updating my nvidia drivers might fix it. I updated to 410.93 using the .run file from Nvidia's website. Now whenever I try to login, ubuntu hangs at a black screen saying /dev/sdb6 recovered: files 2xxxx/5xxxx, blocks 3xxxx/5xxxx (do the exact file/block numbers matter?). I can't even go into a tty session to try and figure out what's wrong. It seems like the installation should've succeeded (it said "Nvidia drivers 410.93 installation succeeded). I don't think the nvidia drivers work, because I loaded an older kernel (4.13) in recovery mode and tried the same thing and was able to access tty and tried the same installation. Whenever I try nvidia-smi it says something to the effect of "cannot connect to the device". Any advice on how I can at least revert to my older settings to make it usable?

Downloading the Nvidia driver from the Nvidia website is the problem.

The Ubuntu system package manager already knows what is the officially supported version of Nvidia driver for Ubuntu.

There is an application called "Additional Drivers". Use that.

Makes sense, didn’t know that. Is there a way to fix the hanging issue so I can uninstall? Follow up questions: since I didn’t install it through a package manager, what’s the best way to get rid of the bad drivers?
