Every time I would boot the computer it would go to the screen with the Linux Mint icon and then it would go to static. It looked like the old TVs when the channel would go off the air.
In order to get into the system, I had to reboot, hit Esc, and choose the restore option. Then I would be able to log in. At which time it told me that I was running without video drivers. If I clicked on the video manager it would tell him I didn’t need any drivers.
The problem is that the Linux Kernal I was using did not support my laptop. So the solution was to update the Linux Kernal to the newest Kernal, which right now is 5.15.1.
Now, how to you do that? This article gives you the basics: https://www.fosslinux.com/7167/how-to-upgrade-linux-kernel-in-ubuntu-and-linux-mint.htm
You can skip steps 1, 2, and 3. After 2021, you might want to double-check for the latest Kernal.
Of course, the article is old and the Kernal is old. So on step 4 substitute the following: (You can copy and paste it in the terminal, it will download all four of these).
wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15.1/amd64/linux-headers-5.15.1-051501_5.15.1-051501.202111061036_all.deb
wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15.1/amd64/linux-headers-5.15.1-051501-generic_5.15.1-051501.202111061036_amd64.deb
wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15.1/amd64/linux-image-unsigned-5.15.1-051501-generic_5.15.1-051501.202111061036_amd64.deb
wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15.1/amd64/linux-modules-5.15.1-051501-generic_5.15.1-051501.202111061036_amd64.deb
Step 5. Now install the downloaded packages. Copy and paste in terminal:
sudo dpkg -i *.deb
Step 6. After successful installation, reboot your machine.
It solved my problem, I hope it fixes yours as well.
