@JusGellin open terminal and run 2 commands: free command and BTOP. Clues?
My personal experience might help as its simple.
I, personally, do this for every PC or VM for last 3.5 decades: create a SWAP partition that is the size of machine's RAM. Almost every forum distro will setup and use it at every boot; if it discovers a partition present, automatically.
Many years ago, performance testing showed that SWAP partition was slightly faster than using swap-file.
In VMs, the qcow is partitioned for a SWAP partition (at size of virtual machine's RAM) and a Persistence partition. Thus my VMs tend to mimic the real (host) PC's system drive.
I use this instead of using a ZRAM approach because it does not use RAM for swapping. BUT, I also recognize that ZRAM offers a performance benefit as it is RAM based.
For using a file for swap, merely google 'swap file creation in linux terminal'
Hope that helps to arrive at a simple organizational layout.
Once I got it working(SWAP partition), it works well on a low memory laptop that has just 4G memory.
Thanks for your tips on this.

@rockedge may be needed to verify. I am not in a position to test at this point as I am away from my home test PCs.
THANKS, for pointing this missing operations out, as I will pay more attention specific to this in my future tests.
On this laptop (BKWP64 v1009 via its ISO file boot) this is what it sees OOTB. I have seen this so much in the past, that I rarely review during testing.
Code: Select all
# swapon -s
Filename Type Size Used Priority
/dev/sda6 partition 8397820 5257252 -2
FYI

How can I change the time zone?
Just from a command would be fine since it is needed only for the initial installation.
Thanks

@JusGellin
create a symlink:
Code: Select all
ln -s /usr/share/zoneinfo/America/New_York /etc/localtime
Or open /etc/rc.conf
and modify line 20 and un-comment:
Use your own timezone. First method is recommended.

This is the one I used. It works
Thanks

Now that I know to turn the swap on, I noticed that it makes its own swap automatically without making a special partition for it.
Is this the case for all KL's?
Thanks

Yes.
I usually will make a swap partition that gets detected and used.
