I removed Intel HD graphic default driver and can't log into GUI even after reinstalling the driver

A few days ago I realized my newly installed Linux Mint 19.3 doesn't handle screen scrolling every smoothly (it scrolled, but the displayed content looked torn up as you scrolled).

After a few Googling, I decided that I wanted to uninstall whatever the graphic driver and reinstall it. After I did that and rebooted the system, I couldn't log it. It hangs at the graphical login screen, but it doesn't recognize at keystroke except for the Fn keys (e.g turning the keyboard backlight on/off. But even after tens seconds, it stops recognizing even those keys and goes completely unresponsive).

I am still able to open the GRUB advanced screen to select a different kernel or go to the Recovery menu call up the root cmd. I have tried to reverse what I did but the system still hangs after it's shown the login prompt.

Here are the exact commands I ran that led to the disaster:

Quote:

# check the current system driver inxi -Fzx sudo lshw -C video grep modesetting /var/log/Xorg.0.log # I tried to remove the xorg driver, but it said it already installed sudo apt-get remove xserver-xorg-video-intel # So I did the reverse, installed the driver to see what happened sudo apt-get install xserver-xorg-video-intel sudo apt install xorg-video-abi-23 sudo apt install xserver-xorg-core sudo apt-get install xserver-xorg-video-intel grep modesetting /var/log/Xorg.0.log sudo reboot

This is how the system configuration looks after I do a 'inxi -Fzx'. Sorry I can't figure out a way to get the texts so here is the screenshot of that. The graphic drivers are now all N/A. They were i915 (or KMS) previously.
