gksudo does not run in terminal - display can not be opoend

Asked by BlauesEi

ubuntu 12.4 with gnome3 desktop

Hi,

I can not start applications like gedit or nautilus with admin rights in the
gnome-terminal.

gksudo nautilus

After the password entry I get the follwoing error:

Could not parse arguments: Display can not be opend

When I repeat this command in the same terminal window
gksudo nautilus
I get the following error:

** (nautilus:971): WARNING **: command line »dbus-launch
--autolaunch=969937dd922ac0603700cc724bee97a8 --binary-syntax --close-stderr«
has been canceled with Null unequal exit state 1: Autolaunch error: X11
initialization failed.\n
Could not parse arguments: Display can not be opend:

It's the same with
gksu and
DISPLAY=:0 gksudo nautilus

Its the same when I change user to root.

When I try to run it via the alt+F2 command entry window nothing happens.

Could you please help me solving this problem?

If you install pcmanfm then run:

gksudo pcmanfm

Is it ok?

Can you also give the output of:

lsb_release -a; uname -a; apt-cache policy nautilus

Thanks

Package gksudo is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

Hi,

thank you for all your answers.

I found the solution:
I have had after successive upgrading to ubuntu 12.04 still an old package vinuxscripts (http://vinuxproject.org/) from ubuntu 10.04 on my system.

this package is at the moment only for ubuntu 10.04 valid.

It replced the gksu package.

After removing the package vinuxscripts and installing package gksu, gksudo and gksu are working.

Certainly I have to use gksudo with DISPLAY=:0 gksudo.

if you know how I can use gksudo withoud DISPLAY, please feel free to tell me that.

have a wonderful day
