"kwrite /etc/fstab" fails

[mab33]

Wanting to change /etc/fstab, I fired up kwrite, but it failed to open:

[root@localhost ~]# kwrite /etc/fstab
No protocol specified
kwrite: cannot connect to X server :0.0

  What on earth is that all about?!

[mab33]

P.S. I should have said that I'm using the latest PCLinuxOS 2010 - fully updated.

P.S. (2)  KDE version

The command in a root terminal is dbus-launch kwrite

looks to me that you did the following:
you were in your user account, then opened a konsole, then "su -" and entered your root-pwd, then "kwrite /etc/fstab"

the error message suggests that you did not provide X-access to root.
try this from a konsole in your user-account:

Code: [Select]

xhost +
su -
{and enter your root-pwd}
kwrite /etc/fstab &

-p.

I am having the same problem. I tried "xhost" and "xhost +" and got

No protocol specified
xhost:  unable to open display ":0.0"

More options to edit /etc/fstab.

ALT-F2 runs Krunner and type kdesu kwrite /etc/fstab (works here).
Konsole (non-superuser mode): type kdesu kwrite /etc/fstab .

I'll try the kdesu approach when I get back to base. (I'm away with non-PCLinuxOS laptop at the moment.)

But with Mandriva I can do:

   [mab@laptop ~]$ su - root
   Password:
   [root@laptop ~]# kwrite /etc/fstab

[mab33]

The command in a root terminal is dbus-launch kwrite

Never heard of that!  With Mandriva I can simply do:

   [mab@laptop ~]$ su - root
   Password:
   [root@laptop ~]# kwrite /etc/fstab

can you log from the GUI in root account? its been my experience that error msg shows up when "~/.Xauthority" text file is missing.

a simple test to show this.

[ink@kdi ~]$ mkdir test                                  <---- create a new folder
[ink@kdi ~]$ cd test                                      <---- cd to new folder
[ink@kdi test]$ export HOME=/home/ink/test/   <----make new folder home folder
[ink@kdi test]$ kwrite                                    <----- run kwrite with new home
No protocol specified                                      <---- error
kwrite: cannot connect to X server :0.0             <---- error  
[ink@kdi test]$ cp  /home/ink/.Xauthority .         <--- copy the txt file "old" to "new" home
[ink@kdi test]$ kwrite                                      <---- kwrite works

Make it simple, to copy for your user konsole

Code: [Select]

kdesu "kwrite /etc/fstab"

[mab33]

Even if "kdesu kwrite /etc/fstab" works, the problem I would have (if kdesu is going to ask for the root password each time) is that - when starting with a new installation - there are a number of root files I need to modify.
    So far I've been able to go into root mode, then simply, issue several 'kwrite' commands.
I really don't want to keep having to enter the root password for every kwrite.

On the other hand, if - when in root mode - I can keep on issuing the 'kwrite' as "dbus-launch kwrite". then that would suffice - if KDE 4.4 is not going to allow any other arrangement...

   [root@laptop ~]# kwrite /etc/fstab

exactly this command sequence also works in PCLinuxOS, just did it myself. Do you enter this sequence in a terminal of your own installation or is this a remote login via ssh? In the latter case you need to login with ssh -X to have GUI support.
-p.

How about this in a terminal?

Code: [Select]

su - then password,  then

Code: [Select]

kwriteWorks for me.

   [mab@laptop ~]$ su - root
   Password:
   [root@laptop ~]# kwrite /etc/fstab

exactly this command sequence also works in PCLinuxOS, just did it myself.

And you should even be able to simplify it:

   $ su -
   $ Password:
   # kwrite /etc/fstab

worked a minute ago on my box. The hyphen seems to be necessary though in this incarnation of PCLinuxOS. (It makes the root shell a login shell.)
