[SOLVED] Problem with running GUI apps as root

Zibi1981 · 2010-09-25 09:43:16

Hi,

I have a serious problem with running any kind of software having GUI as root, which is indispensable for editing system files. For example I want to edit /etc/pacman.conf file with KWrite, and here's what I get

[zbyszek@barca ~]$ xhost +
access control disabled, clients can connect from any host
[root@barca zbyszek]# kwrite /etc/pacman.conf
kwrite(11282): Session bus not found
KCrash: Application 'kwrite' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/root/.kde4/socket-barca/kdeinit4__0
Warning: connect() failed: : Nie ma takiego pliku ani katalogu
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi directly
drkonqi(11284): Session bus not found

Can anyone help me with this? Can anyone tell me how to login as root?

Thank you in advance.

What's wrong with nano, pico, vim?

Don't tell me you really need a GUI to edit a few system files, being an Arch user...

Well, I'd prefer KWrite, it's far more convenient. Linux is all about choosing the software you prefer, doesn't it? I used to use Vim, but now it seems more complicated. For example when I open a file and press i or INSERT vim does not go to "edit mode". Strange, but whatever, as I have always preferred KWrite, which is my favourite application for editing system files.
So how to run KWrite as root and how to login as root? Can someone explain that to me?

Try running 'xhost +' as root.

Maybe vim is in edit mode when you press 'i' but it doesn't show '-- INSERT --' at the bottom of the screen.

That's how classical vi works and not how vim works. I can only guess Zibi1981's vim stuff is corrupt.

Put 'set noshowmode' in your .vimrc and try it yourself.

I stand corrected.

O.K., but how to run KWrite as root on my account??? That was my main question

Here you are

[root@barca zbyszek]# xhost +

[root@barca zbyszek]# kwrite /etc/pacman.conf
kwrite(12941): Session bus not found

You run either as root or as a user. You can sudo to get more privileges as a user, if that's what you're asking.

Zibi1981 · 2010-09-25 10:23:20

What I want is:
1. login as a normal user to my account, as I am right now in fact
2. open terminal
3. change to root account in the terminal
4. and finally run KWrite from there
The command xhost + used to do the job before, but now it doesn't work any more.

When using KDE logging in as root is possible if you make a change in kdmrc.

The file to change is in..... /usr/share/config/kdm/kdmrc...

Scroll down to ...Allow login as root=

Enter : Allow log-in as root=true....

This will provide a log-in as root with a root password.

i suppose you are running kde, you can open gui programs with sudo when using "kdesu" command instead of the "sudo" command.

How do you become root in the terminal, by "su -" or "su"?

If you used "su -" you changed the environment to the root user's one. This may cause the problems you encounter (at least it does so here). I haven't used "xhost +" since years so I cannot tell whether its behaviour has changed lately. But I usually become root by the "su" only command in case I have to run a command as root from the terminal in my current user's environment.

I cannot test this with kwrite currently as I do not have kde installed. But similar actions worked earlier all the years before.

Often GUI apps won't run as root in KDE unless you prefix it with dbus-launch.

Try running:

root@barca zbyszek]# dbus-launch kwrite /etc/pacman.conf

I still cannot run KWrite as root in terminal, when being logged as a normal user

[zbyszek@barca ~]$ xhost +
bash: xhost: nie znaleziono polecenia
[zbyszek@barca ~]$ su
Hasło: 
[root@barca zbyszek]# dbus-launch kwrite /etc/pacman.conf

Don't use root.

Did you read the link karol gave you? That should have solved your sudo X errors...

EDIT: By the way, that statement is self-contradicting. Unless you meant from a normal user's X session.

Yes, I have read it, but it doesn't help me at all, as I don't have /etc/sudoers in my system.

Finally! Briefly and to the point. Thank you very much skunktrader

Wha?
I thought you have sudo installed?

Nah, it's fine.
Hope I didn't come off as an ass or something.

Save yourself much grief... never login as root, use sudo. I say this from personal experience early in my Linux 'life'.
