hi, in new installation of EOS(just before reinstalling OS, everything was fine), one of CPU cores always have high usage even in idle after turning on laptop and i feel my laptop got much slower + i have very low fps in games due to cpu usage. tbh have no idea how to trace issue or what log/outputs should i post here
htop screenshot:
Your screenshot application flameshot
is using a lot of CPU according to your screenshot. Does it happen always?? Replacing that application might help you.
Also, your laptop is currently not idle, CPU is almost at 20%. At this CPU usage, just one core is used and others are idle to optimize power consumption.

flameshot got like that just when i pressed hotkeys to take screenshot, so no its not hapenning always
also, i just rebooted laptop and let it sit for awhile, didnt open any applications etc.
here’s my i3 config
#autostart
#exec --no-startup-id hsetroot -center ~/.wallpaper.png
#exec --no-startup-id xsettingsd &
exec --no-startup-id nm-applet &
#exec --no-startup-id picom -b --e --blur-method dual_kawase --blur-strength 7
exec --no-startup-id /usr/lib/polkit-gnome/polkit-gnome-authentication-agent-1 &
#exec_always "feh --bg-scale ~/Pictures/wal_6.jpg"
exec_always "setxkbmap -layout us,ir"
exec_always "setxkbmap -option 'grp:alt_shift_toggle'"
#exec "./home/rootiens/cfw/cfw"
exec_always "xrandr --output DP-1-1 --right-of eDP-1-1 --auto"
exec_always "~/.config/polybar/launch.sh --forest"
There should be an app that uses CPU at idle, find out what that app is and why it is consuming CPU.
This is true for any OS and computer.

htop doesnt show anything (according to my knowledge atleast)
anyway to trace and find that app?
I’m not sure, but I use btop
instead of htop
. If you post a screenshot, I can take a look.
Someone else might know other methods.

ok let me reboot laptop since i’ve opened lots of applications right now and results might not be correct
idk if its worth mentioning or not
booted ISO from USB and took screenshot rightaway
Can you post a btop
screenshot, it shows total CPU usage along with graphs, that makes it easier to interpret for me.
Install by using
sudo pacman -S btop

there you go
right after logging in
also for anyone else if interested in htop
yes, this is definitely strange for sure, can you keep this on for 1-2 mins and then post the screenshot again? We can see the CPU graph and how it changes.

in live iso? or my actual OS?
Your OS where you are posting screenshots from. Just keep btop running for 2-3 mins, it will show trends in form of graph.

ok, i’ll reboot and run it again for better “raw” results
no need to reboot, just keep btop running for a while and post screenshot

sudo pacman -Syu linux-lts linux-lts-headers nvidia-lts
sudo grub-mkconfig -o /boot/grub/grub.cfg
Then reboot & select LTS kernel from grub menu.
