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:

5

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

6

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?

7

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

8

Also your system is already using swap

9

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

10

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
