 CPU and RAM usage (Not Idling Normally)

(1/2) > >>

ShadowLordSora:
Hello everyone,
I have been using siduction for a while now and It's only after a fresh install that I have been having a problem. The problem is that my CPU an AMD Ryzen 3600X  and my RAM 2x8GiB sticks as a G.Skill FlareX 3200C14 has been not idling normally and what I mean by that is that when I first boot into my system my RAM and CPU usage are normal (between 1%-10% for CPU and between 5%-10% for RAM) then after about 30 seconds the CPU will got up to 100% and the RAM will got up to 50% (this is with nothing running).

I have tried these things,
1) Changing kernels, starting with 5.7.3, then 5.8.3, then 5.8.16 (which is with the latest ISO I have on hand), then 5.9.12, then 5.10.3 and now 5.10.4 (currently running)
all of these kernels have the same problem with the CPU and RAM.

2) Booting into a live ISO and running htop, this in turn the CPU and the RAM are running normally.

I can't post any screenshots as the files are too big

Thanks for reading.

devil:
Do CPU and RAM usage stay this high? For how long? What does htop say about the processes driving the CPU load? (screenshot please)

ShadowLordSora:
Hello Devil,

The CPU and RAM fluctuates, so for CPU 100%-10% and RAM 50%-10%. This fluctuation happens for hours on end.

i am not familiar with DisplayLinkManager (what are you using it for?)

google search provides some hits, for example this one:

Hello,

I use DisplayLink to run a USB 3.0 Monitor, the monitor I use runs a conky. I install the DisplayLink driver using a shell script which I found on github and I use the ArchWiki to help has well, like making the monitor run on start up.

The conky on my 2nd monitor is where I started to notice the problem I'm having.
I have attached a screenshot of my conky using the 5.10.3 kernel, showing the CPU and RAM usage.
