I’m not using zswap. > Filename Type Size Used > Priority > /dev/dm-1 partition 10485756 > 0 -2 I don’t recall ever having seen it actually use any swap, but that may just be me not remembering something that didn’t seem important at the time. Rick PS: I did manage, just now, to force it to swap a small, but non-zero, amount by opening lots of tabs in firefox. So it will use a “-2” swap partition if it has to. For what it’s worth, I noticed that firefox got kinda slow, but it didn’t freeze.
