I’m still stuck with an older laptop (Acer Aspire 5740G) on which I’m currently also switching from the old openSUSE install to the latest version of Manjaro. It works fine for the most part except for the curse of most laptops: It only has 4 GB of RAM, which is so little the memory fills up just by opening too many tabs in Firefox or doing other trivial tasks.
I remember a few years ago the Linux kernel announced support for memory compression. While I don’t need that on most of my devices I could definitely use it for this laptop. But I never used the feature before and have no idea how to enable it. What’s the correct way to turn on memory compression support in the kernel on Manjaro?
