Some time ago I noticed a lot of ram(1.8/8GB) being used when my system was idle with only a day of uptime. I had to reinstall my Ubuntu because of some reason and now the ram usage has risen up much more. I only have a 26 hours of uptime and this is the result of free -m when my system is idle

          total        used        free      shared  buff/cache   available
Mem:      7738        3622        2810         136        1304        3720
Swap:     2047         271        1776

This is 3.6GB/8GB when my system is idle. The ram usage remains same when I turn off all the extensions too.This is way too much. I'm also posting a screenshot of processes running at this time. And this is not that my system automatically adjusts ram when I open applications, I'm only able to open very limited applications from before. This is way more than windows has ever used on idle.

Can someone please help me avoid this issue?

  • I am trying to understand what you are illustrating with the screenshot? was that at a different time as the free command?.... the screenshot barely shows half a gig being used... – WU-TANG Oct 09 '20 at 00:22
  • your gnome-shell is using only 173MB of ram.. I don't see any problems – Lews Oct 09 '20 at 01:22
  • @WU-TANG That had a time difference of max 30 sec. I don't know which processes are taking my ram but they somehow are – Heisenberg Oct 09 '20 at 02:01
  • @Lews I don't have a problem with gnome-shell but ubuntu in whole – Heisenberg Oct 09 '20 at 02:02
  • Are you assigning/sharing memory to graphics??? that usually comes off the top though... But how much memory do you have consumed when you boot and log in? – WU-TANG Oct 09 '20 at 02:16
  • to know which process in consuming more memory you just need to type **top -n1 -o %MEM**. Try to past here the output. – Lews Oct 09 '20 at 02:21
  • @WU-TANG I don't know what you been by assigning sharing memory to graphics. I don't have a external graphic card and haven't done anything to change configurations of the same. I have about 1.1GB-1.2GB when I boot in. – Heisenberg Oct 09 '20 at 02:36
  • @Lews I'll paste the output here when my system starts eating ram again. I just restarted so that can can a while. And I tried the command but it doesn't anything different from system monitor feed. – Heisenberg Oct 09 '20 at 02:37
