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.

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

I don't know how to setup anything in that list, exept to install earlyoom to kill the largest procsses when ram and/or swap runs low.
So anything else is reduntant as far as i'm concerned, and was asked to write this tuturyial by someone in said disscussion to install earlyoom by default to help others, and didn't even knew about this section, nor used knowinly, nor written a tutorial before.

If you can do better go right ahead, or responed with a better writion one, the fact it did not take me 3 weeks to write this is a mirricle by it's self (creative or instructual writing is not my strongsuit), this curranly emotiol get the point writting hence the quick and lenthy response.
