My i5 processor is usually on 1-2% system usage when idle use. Now it is stuck at 60-80%. In Resources the largest consumpter is shown as “System Resources” – around 25% (I actually just shut down edex-ui that was running in another workspace and it dropped down to 39/12%, which is still abnormally a lot). May I be infected with a miner?
We cannot really judge. Only you can do the hands-on checking for the cause. I think btop may provide some information as to the processes involved.
Once you know the processes involved we may be able to provide some additional insight.
Mine shows this right now. (of course the individual cpu percentages bounce a lot)
I would start by running the normal top program that focus on processes.
Try top -i that will only show processes that are using CPU time.
I checked btop and top. For some reason the program I’m working on that I closed was still running and consuming CPU time. It was shown as taking 184.1% CPU in top due to some glitch and seemingly correct 26.6% of CPU lazy in btop. I stopped it and now CPU consumption is normal.
