VM or direct on hardware?

systemd is the main system daemon and will always be quite busy, in a VM they will appear more so (less resources as hardware being shared by host)
Does it settle down if you leave it a few minutes?
it could be updating cache files etc in the background

xdg-document-portal is used by flatpak and snap apps to allow a program to elevate privileges outside of their sandbox (opening and saving files for example) and it uses a systemd call to achieve this.

This explains why those two processes are using high cpu cycles, but you’ll have to dig deeper to find the actual program that is causing it.

You will know what you have installed that might cause it, the other thing to check is it set correctly for your desktop (gnome, KDE etc);

i am using xfce4 DE.

The process is the same, I only linked for reference of ‘how’ to check these things.

Have you installed a flatpak app or a snap app?
If you have, that will be the issue, and its not part of a standard Kali install so you have to figure it out.

No, i am not using any flatpak app or a snap app.

You can use ‘tree view’ to get a better ideas of exactly what is using resources using task manager;

That process is a file system mount point, are you running from an external drive?

11

no, kali is running from internal ssd.

Well if your not using flatpak or snap apps, then you shouldn’t need it, try restarting it;

systemctl --user  restart xdg-desktop-portal

Hopefully that will reduce its resource usage..
Check your start up programs too, something must be calling it..

dude, fusermount3 -o rw,nosuid,nodev,fsname=portal,auto_unmount,subtype=portal -- /run/user/1000/doc this service is consuming too much cpu .

I run that command but it did not fix it.

The real question is does it seem sluggish?
and if you leave it for 5-10mins does it then drop cpu cycles?

and again, check what you have enabled and starting up with your system, databases, and file servers we use for tools can take resources.

Is this a fresh install, or have you had it installed for a while, the first instance warrants exploration, the second, well who knows what you have installed or set running in the background.

Check your logs, no one else can see your machine or diagnose it via a forum.

Sometimes it is simply easier to ‘start again’ from a fresh system than to try and remediate a random or obscure issue. If you want the learning experience and have the time, go for it, but for me, any OS is just a tool to get my work done, so beyond a certain point a 20 - 30 min install against days of head scratching seems prudent.
