Why my Manjaro only use 1gb of ram ? my Laptop ram is 2gb

Please help me. i just installed latest manjaro kde yesterday, and i notice that it only use 1gb of ram despite my laptop(asus x441s) having 2gb of ram!
the ram usage on system monitor never goes above 1gb
i consider switching to manjaro xfce but many youtube videos say that kde is lighter than xfce now…

No, the title does not say it all. :wink:

Please post your system info as outlined here:

I don’t see anything wrong from the screenshots, perfectly normal. It detects 2GB. If you wonder why it says 1.8, calculate this: 2000000000 / (102410241024). Not all RAMs are equal, some calculates with base 10 (multiple of 1000), some with base 2 (multiple of 1024). Hence exact calculation is impossible. Furthermore, integrated GPU may eat some of those, probably a small amount like 64MB, usually available and configurable in BIOS.

sorry im new to this forum :ok_hand:

no, im wondering why my sytem doesnt use ram more than 1gb the remaining ram is useless then

Your Manjaro install sees 1.83GiB (which is the same as 2 GB) RAM and uses 1.22 GiB of those.

So what’s the issue?

You wanna hog your system? Easy. Open Slack, Discord, VS Code and Google Chrome. That 2GB will suddenly vanish.

Also your system is already using swap

bruh, i already tried that before posting this. maybe i need to reduce swappiness ?

yeah i consider switching to manjaro xfce. whats your opinion ? will xfce run faster on 2gb ram ? im still confused there are many articles and videos that says kde is lighter than xfce now

The responsiveness appearance of a DE can be misleading a bit because of the animations or the way some transitions are made.

From where i stand there are no more differences in that regard. KDE Plasma, Gnome and Xfce are to a point that for a complete DE are absolutely fantastic, and the only thing that makes a difference is the workflow of the user and, in your particular case, a device that has less ram than most such devices have by default this days.
You will actually see a difference with a SSD and probably update the ram to maximum that can handle (from what i understand is 4 GB), but otherwise, not sure if even with a Openbox or i3 setup you will feel like is super fast …

ok then, i will be saving for an ssd and ram. big thank you to all who helped me. i guess this is closed
