CPU and RAM usage (Not Idling Normally)

[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.

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

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.

Hello again,
I just did a test by uninstalling the DisplayLink driver and I'm still having the same issue, just want to run a test to help anyone out.

according to your screenshot it might be gpu-ls.
interestingly it is only listed with <10 % cpu

Code: [Select]

$ apt-file search gpu-ls
ricks-amdgpu-utils: /usr/bin/gpu-ls

i suppose that this utility package needs some more attention. maybe particular settings? maybe there is a known bug?

Hello absolut,
Removing gpu-ls has fix the idling of my CPU and RAM. Thank you for you help.
