I'm a bit unsure about what you're asking for. To avoid the error, you should run it with root privileges with a command like `pkexec gparted`.

What's the advantage of pkexec over sudo in this case?

If you want to run a GUI app, e.g. Firefox as user B, while you're in a user A's X session, you need to do something like this:

xhost + ; gksudo -u B firefox

xhost + is a sledgehammer, I anyway use it that way, xhost could be used smarter.

I haven't tested it, but xhost seems a bit superfluous in combination with gksudo. Doesn't gksudo take care of setting the X auth itself? mvg, Guus

It doesn't.

[rocketmouse@archlinux ~]$ gksudo -u chuser qupzilla [rocketmouse@archlinux ~]$ xhost + ; gksudo -u chuser qupzilla access control disabled, clients can connect from any host QupZilla: 0 extensions loaded [rocketmouse@archlinux ~]$ xhost - access control enabled, only authorized clients can connect

Ok, so if you use gksudo and then launch an xterm, you get an display error? Sounds a bit odd, for a gui to sudo... (access control is more then just enabled/disabled ;-) ). mvg, Guus

Hi, should gksudo be able to open a GUI for another user without the need to take care about the client authentication? $ gksudo --help GKsu version 2.0.2 Usage: gksudo [-u <user>] [options] <command> [snip] --login, -l Make this a login shell. Beware this may cause problems with the Xauthority magic. Run xhost to allow the target user to open windows on your display! [snip] There's no "Xauthority magic". If I use gksudo _without_ the "login" option, there nevertheless is the need to use xhost. https://mailman.archlinux.org/pipermail/arch-general/2014-July/036833.html Regards, Ralf

You need to install and run a polkit authentication agent.

No, it isn't.

% cat /usr/share/applications/gparted.desktop | grep Exec Exec=/usr/bin/gparted_polkit %f

[rocketmouse@archlinux ~]$ grep Exec /usr/share/applications/gparted.desktop Exec=/usr/bin/gparted_polkit %f But software as e.g. menulibre and cinnamon-menu-editor do show /usr/sbin/gparted %f, so assumed I would use xfce4-appfinder to launch gparted on JWM, it would launch /usr/sbin/gparted %f and _not_ /usr/bin/gparted_polkit %f. I kept the default, didn't edit this entry, it definitively is /usr/sbin/gparted %f . IOW the menu's default might be /usr/bin/gparted_polkit %f for the DE you're using, but for e.g. Xfce4 users (xfce4-popup-applicationsmenu and xfce4-popup-whiskermenu) it is /usr/sbin/gparted %f.

I just launched polkit from the xfce menu and it ran /usr/bin/gparted_polkit %f as expected. I wouldn't use anything who's authors decided to ignore the system and run whatever the hell they wanted.

My current Arch Linux + Xfce4 was installed in February 2013. It's up to date, but there were a few changes in the meanwhile (e.g. for the FHS). Perhaps there was a change from /usr/sbin/gparted %f to /usr/bin/gparted_polkit %f, but then the updates didn't modify an existing Xfce4 menu.

I have already installed polkit-gnome but I am using XFCE :D On Thu, 10 Jul 2014 20:22:29 -0500 Doug Newgard wrote:

You shouldn't need any of that, just the authentication agent as I already said.

And please don't top post.
