[SOLVED]xorg-server 1.18.1-3 & plasma 5.5.4-1 - high CPU usage
Hi guys,
since this weekend, I can see that xorg and plasma need a lot of CPU.
I don't remember how it is usually but I always have a terminal with htop open and usually, Java takes a lot of resources, I rarely see xorg/plasma at the top.
Now, they are constantly at the top.
I have two plasma process, one uses around 44%, the other one 25%. Xorg uses around 30%.
Does someone have an idea on how to find what's happening ? I restarted my laptop and nothing changed. Those processes have more and more CPU usage after some time.
Thank you.
edit : even kwin_x11 is there for around 8% CPU usage, it is the first time I see this process.
SOLVED : mentionned in my last post. plasma crashed and now everything is fine.

Are you sure that it's not just some plasma applet that's causing all the mess? They do behave a bit randomly.

How can I find which ones are used ? I never added an activity/applet or something like that.

I clicked on the upper left corner of my screen and then "show desktop". After that, plasma crashed and everything seems to be fine, I have the usual java 8 and chromium at the top.
xorg-server takes around 0.7% of CPU, same for kwin_x11.
Let's see if that stays like that.
Thanks.

It's most likely not that, then. Just for future reference: simply remove one by one, and see if it makes any difference.
Other most common thing that I find to be clogging the session might be kactivitymanager. Check your htop and see if it too is high. If so, try resetting activities by deleting related config files in ~/.config
