[Solved]Polkit agent in kde6 wont start

[mirekm]

Since upgrade of kde into version 6, I get a problem with polkit agent.
When it try to start it get an error, and stops. Thus I cannot suspend from kde, and so on.
Have no idea what is going on, maybe someone had similar problem?

On Gentoo's KDE wiki ( they got it from KDE documentation ) when starting with no display manager ( this is how I work ), it mentions to start plasma with "dbus-run-session startplasma-wayland"

but I later found I was unable to use the command "pkexec" or edit any files ( using kate for example ) that didn't belong to me ( like root files ).

Polkit agency wasn't running. I later just "exec startplasma-wayland" and since then it's worked for me as polkit agency is there

I think when you login in, there is already a dbus session running and that's the session polkit agency is running in

doing "dbus-run-session startplasma-wayland" starts another dbus session but polkit agency doesn't start in that session for some reason

mirekm,
We recently had a post about this:
https://forums.gentoo.org/viewtopic-t-1170707-start-0-postdays-0-postorder-asc-highlight-polkit%2Bagent.html
Maybe look at that and the troubleshooting methods mentioned to see where your issue might lie. It may or may not help but I thought it worth mentioning. The troubleshooting steps might be helpful to you in isolating your issue. First, make sure you ran dispatch-conf or etc-update recently to eliminate stale config files as the cause.

I found the root of the problem.
Until now for proc file system I used mount option hidepid=2,gid=polkitd.
This option hide all pids that don't belong to user. With gid=... it allowed polkitd to access all the pids in the system.
And it worked.
Because it don't work anymore, I had to disable this mount option, to get polkit-kde-agent.
