Adding memory protections to avoid low RAM lockups

[fosslover306]

Install earlyoom, it automatically kills the top process to free up RAM "sudo apt-get earlyoom" or search for "earlyoom" in the software center.

While you are following this tutorial installing Zram is also a great idea if you don't mind a 4% or less CPU overhead to increase your computers RAM by 40-60%, and it's way faster and more responsive then swapspace, while sparing your SSD.

It was even at the top of https://github.com/orgs/linuxmint/discussions

If you want to make a tutorial, you should add more details on how to set it up (RAM and swap limits, which processes to avoid closing and which ones to prefer) and examples for common settings.
Maybe even some alternatives to that software, other suggestions on how to optimize RAM and swap usage, and even mention setting the RAM limit used by Cinnamon before rebooting it, etc.

Another useful thing if you are limited on RAM but not too much on CPU is ZRAM, this also limits the use of swap which slows down using it on HDD or can decrease disk life on SSD disks (significantly on low-cost customer SSDs): https://forums.linuxmint.com/viewtopic.php?t=427964

Place in /etc/default after unzipping the file, make sure that the config file is fact their before overwritting it, or copy paste the arguments from this into yours both methods work.
