IMPOSSIBLE OPEN FILE WITH GEDIT COMMAND

ciampucci · April 1, 2009, 10:35pm

Hi,
with opensuse 11.1 (gnome desktop environment) I receive a strange message when trying to open a file, like fstab, with gedit.

If I type:

sudo gedit /etc/fstab

after entered the password I obtain this:

Gtk-WARNING **: cannot open display:

I looked for an answer in the web but nothing. Have you got any idea?

Try gksudo gedit [filename].

ciampucci · April 1, 2009, 10:55pm

are you thinking about the similar command in kde for kate?

kdesu kate .....

instead of

sudo kate ....

could be. I try.

Hi
Use gnomesu instead;


gnomesu gedit /etc/fstab

I think this came up last week too. As you are trying to load with ‘sudo’
try, instead, ‘gnomesu’ or ‘kdesu’ depending on if you are using Gnome or
KDE. I think you’ll enjoy the results. The reason is that you need to be
able to connect to your desktop (owned by your user) as ‘root’ (the user
you are becoming). There are other ways, but gnomesu and kdesu make it
easy for you:

gnomesu gedit /etc/fstab

Good luck.

So what in practice is the difference between gnomesu and gksudo? I’ve always used gksudo, and it seems to work, but lots of people keep recommending gnomesu. Puzzled…

malcolmlewis · April 1, 2009, 10:59pm

Hi
gksudo is long gone… gnomesu now.

Thanks - must’ve been confusing things with ubuntu, in which it still works. I’ve been playing with KDE so much I hadn’t noticed I was telling people the wrong thing.

:shame:

Sorry everyone!

malcolmlewis · April 1, 2009, 11:18pm

Hi
That it (gksudo) doesn’t exist in the openSUSE distro… the default is
gnomesu.

Isn’t it an Ubuntu thing anyways?

Use gnomesu instead;

Ok, it works. Thanks.

just a little consideration: in Ubuntu I usually use sudo with gedit and it works fine. Why doesn’t work in opensuse too?

because the security model is different in openSUSE and Ubuntu…

many sudo available programs in Ubuntu are NOT available in openSUSE…

it is felt by the openSUSE developer community that the way here is
more secure…(but i can’t explain why)
