cannot open nautilus with gksu

[mc4man]

Don't think it's gksu, just some nonsense with nautilus

Fresh 14.04 amd64 install just now.
Installed gksu, ran command, failed
Added my ppa, updated nautilus to a pkexec enabled one, ran gksudo nautilus, failed, ran nautilus-pkexec, failed on same error
Installed dconf-editor, ran command to open root nautilus, failed
Ran dconf-editor thru gksudo, closed dconf-editor
Now nautilus can be opened as root, both gksudo & pkexec work

It's if nautilus can't get a root gui display until some other root gui has be opened (that also would be satisfied with sudo nautilus

Make startup USB with SDC from trusty-desktop-i386.iso 2014/04/14.
Install trusty to i386 form factor (this case a Dell Latitiude).
Remove USB pen drive/reboot.
sudo apt-get install synaptic
sudo apt-get update
sudo apt-get dist-upgrade
Use Ubuntu Software Center to download ubuntu-unrestricted-extras
reboot

Login: Ctrl+Alt+t and enter-
gksu nautilus

apt will remind you that gksu is not installed.

sudo apt-get install gksu

gksu nautilus..... authentication window asks for password- Enter PSWD> (at this point a blank pop-up comes ups then it dies ,window closes, and leaves the usual error message in terminal.) Ctrl +c and exit gksu.

Run:

sudo nautilus

Works beautiful. Close nautilus window. Then:

gksu nautilus

Works as normal .

The scary thing about this is that after the gksu first fail and then you try 'sudo nautilus' it does not ask for password so I would have to ask if this bug is a security risk.

Regards..

I'll be watching to see if it sticks for a day or so, At the beginnig of your post i had commented there about "sudo -i" then "nautilus" but it did not stick for me.
I like mc4man's lead on nautilus not consitanly grabing root.

Does it work with

sudo -H

and does

rm ~/.gksu.lock

Here is what i get with "sudo -H"

Yes the Nautilus opened in root,
then after "rm ~/.gksu.lock"
I then issued sudo gedit

sudo gedit

^Cme@me-Aspire-M3300:~$

Complete fail so then i issued "gksu gedit" It was trying to start admin privileges then nothing fails, with nothing in the terminal See Attachment.
Ventrical had this earlier also so I close the terminal via <control+c>
Then I issued "sudo -i" then "gedit" worked! (second attachment)
There just seems to me like focus is being lost.

Pretty well the same thing here. Whats happening is that this bug has become random. It will be there on some hard-boots and disappear on others, both 32bit and 64bit.

After installing the final release ISO today I got the errors the first time I entered this but after that first time I got no errors with gksu or gksudo nautilus or gedit.

cavsfan@cavsfan-desktop:~$ gksudo gedit /etc/grub.d/05_debian_theme 

(gedit:7039): Gtk-WARNING **: Calling Inhibit failed: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files

So, it appears to fix itself after the first time.

EDIT: I take that back I got the error again after saving a text file gksudo gedit /etc/default/grub. It was OK until I saved it then it gave the error.

Strangest thing. I also had this issu while trying to get nautilus-gksu to work. The thing that solved it for me, was to install "Samba". So now it works to launch nautilus with gksu from terminal, and it also works to open as administrator from the right-click menu. gksu gedit also works fine... Seems to be solved for me.
