Re: [SOLVED] Gparted doesn't start

gparted

is a partition manager from GNOME that requires a GUI. Do you have a display server and window manager running?

Re: [SOLVED] Gparted doesn't start

Even if, sudo will drop the necessary environment by default.
gparted comes w/ a polkit rule to elevate itself, if you don't have polkit, you'll have to inherit the (necessary) environment variables (DISPLAY and/or WAYLAND_DISPLAY, perhaps XAUTHORITY and DBUS_SESSION_BUS_ADDRESS) from your GUI session.
https://wiki.archlinux.org/title/Sudo#E … _variables
nb. that IN MOST CASES RUNNING GUI APPLICATIONS A ROOT IS A TERRIBLE IDEA (arguably even gparted should™ not require this but it is what it is…)

Sanity check: what are you going to do with it?
You cannot resize active filesystems in most cases and in most other cases that's not a good idea either.

I'm using Sway, I have Polkit installed
pacman -Qs polkit
local/lib32-polkit 126-1 Application development toolkit for controlling system-wide privileges
local/polkit 126-2 Application development toolkit for controlling system-wide privileges
local/polkit-qt6 0.200.0-1 A library that allows developers to access PolicyKit API with a nice Qt-style API

I'll read the links
