Hello.
From kickoff menu, Openning konsole in super user mode, return 3 errors warning :

Password: 
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
++ logger -t JCD_ETC_BASH-BASHRC '/etc/bash.bashrc - BEGIN'

The errors appear after the password input and before the second line ( instruction logger -t … ) of the file /etc/bash.bashrc

Postscriptum : the first line of /etc/bash.bashrc contains :

set -x

At any moment typing this command :

kf5-config --version

return the same errors :

linux-dpgm:~ # kf5-config --version
+ kf5-config --version
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
Qt: 5.6.2
KDE Frameworks: 5.32.0
kf5-config: 1.0
linux-dpgm:~ #

Any help is welcome.

Ignore that warning, it’s normal when you run Qt applications as root in the user’s session.

Or do you have any real problem?

3

Practically not.
Just the three warning lines.

Thank you for your quick answer.

But is it somethings like a bug ?

No.
Qt just tells you that $XDG_RUNTIME_DIR is not set, and therefore it uses some default directory for runtime/temporary files (/tmp/runtime-root/).

XDG_RUNTIME_DIR will normally be set when you login, but not by “su -”… (though it obviously did in previous versions)

If you want to get rid of the message, you could probably set XDG_RUNTIME_DIR manually if it’s not set before running a Qt application, or not run a Qt application in /etc/bash.bashrc in the first place… :wink:

Btw, it would probably be better not to modify /etc/bash.bashrc, there’s /etc/bash.bashrc.local for local changes…

5

Yes of course.
But I modified it just for seeing where/when the warning come from.

Another derivative question on the subject :
2 laptop with same config ( same install and same update ).
same files :

/bash.bashrc
/etc/bash.bashrc.local
/etc/environment
/etc/profile
/etc/profile.local

/etc/sudoers :

##
## User privilege specification
##
root ALL=(ALL) ALL

Uncomment to allow members of group wheel to execute any command

%wheel ALL=(ALL) ALL

Same thing without a password

%wheel ALL=(ALL) NOPASSWD: ALL

From the kickoff menu, when I open a konsole in super user mode ( konsolesu-2.desktop ) I did not get the warnings on the first computer I configured two months ago.
Have you any idea where I should found the difference ?
I am speaking of the action that open the konsole window ( Not what should happens when I type a command after opening. )

I have been ignoring those messages. Thus far, they have not caused a problem.

7

And where does it come from then?
The default /etc/bash.bashrc does not run any Qt applications, and none of the other default auto-start scripts (like /etc/profile) neither.

From the kickoff menu, when I open a konsole in super user mode ( konsolesu-2.desktop ) I did not get the warnings on the first computer I configured two months ago.

Maybe in your custom Root_Shell_JCD.profile?
In particular the “Command=” line…

8

I got it.

/etc/profile.local source a script of mine to set some env variables.
The sourced script call a kde function to get kde version

**kf5-config --version**

It is the call of this function which causes the three warning messages.
