hidepid is a security feature.
Settings at time of writing:
hidepid=3- doesn’t seem to exist
But there are many issues with it:
Was discussed and attempted in the past:
But never had its own forum thread.
The main issue I remember we had was that
pkexec isn’t compatible with
hidepid, which broke multiple applications.
pkexec however seems to be the only framework that supports showing a graphical password prompt to escalate parts of a GUI application with administrative (“root”) rights under native Wayland.
Running GUI applications as root, commands such as
(lx)sudo gui-application is no longer possible under wayland. (If that works, that is only Xwayland, not native wayland and to be avoided.)
