To put it simply, MHWilds is very messy. One of the recommended fixes for the desktop crashing is to enable zswap, and the arch option I found isn’t available on cachy (it’s actually systemd-swap on AUR, and I’m not sure why I can’t properly install AUR stuff from octopi. Probably missing some steps.)
I can’t simply edit grub because I picked the recommended boot option (and it probably would look different anyway) so I’m not sure what to do OR if it’s even wise to enable that. Need some inputs here.
