Leap 42.3
kernel 4.8.5
KDE 5.32.0 Plasma 5.8.7
X is using 40% plus of my cpu power. This makes the whole system very unresponsive
I checked with top and nothing else except an occasional kwin is using much at all
How can I debug this?

Hi
Sounds like it’s probably tracker running in the background creating an initial index of files when system is idle… You should be able to disable/remove or let it finish…
Using ps aux|grep track returns nothing. Also, this doesnt quit after awhile, its quite constant
If you take a look at the KDE bugtracking system https://bugs.kde.org/ there are many reports of high CPU usage by X, kwin, plasmashell, or combinations thereof…
This one in particular https://bugs.kde.org/show_bug.cgi?id=378010 tracks many non specific cases, maybe something of relevance to yours in amongst it.
Here is what is running

Hi
So if it’s X (Xorg), then look at pstree to see the underling processes?
pstree
pstree -p
pstree -p -H `pidof Xorg` | grep track
Thats a lot of data so i would prefer to include it as an attachment but I dont have perms to do that here
so, here is the data - sorry its long, in fact too long for 1 post
