LL Uses all ram but not swap

[Robert Junior]

Im using Linux Lite in a old notebook to play Minecraft with my little boy.

I made one machine install and every thing works fine, but second machine I suffer with a strange swap problem.

As I know Minecraft Java Edition uses a lot of ram and I can set the amount to reserve for java while starting game.

When I reserve 2GB for java the game loads and I can start play almost all Ram in use and only few mb used in swap.

Swap usage


Different from another machine that swaps grow im a way that seems normal to me like 600, 700, 900MB and keeps a secure amount of ram free. Already tried others swapiness combinations like 10 20 50 70 90, but nothing changes. A see a curious thing in Gparted the swap partition still off and I must enable it with swapon command

Partition boots like this: Swap off when boot


And then after right click swapon the swap is mounted and appears available in htop.

Noticed another strange info at Disks app. the swap allways show as unknow. mounted or umounted state. Unknow Partition


Btw I read something about this distro using a swap file instead partition, but I guess indifferent of type they should appears in use at htop.

Someone can guide me a direction. Im newby in linux but Im not give up a good fight. I really like that in linux.

Thanks you all.
