Arch Linux

This is broken due to the latest dbus changes, not much we can do from the kde side...

The changes in dbus are fine, the problem is that kdesu isn't preserving the information it needs to use it.

It couldn't use it even if it did preserve the environment, since a session dbus-daemon will not let any other user connect, even root.

The proper thing to do would be to ensure root's user systemd is around and set the environment correctly. pam_systemd will do that.

From https://bugs.archlinux.org/task/51453.

Starting from dbus version 1.10.10 I can't run GTK applications, like mousepad, with sudo. Application can't change it setting, and console spamming with one warning message.

dbus latest version on this moment - 1.10.12-1 (I'm on testing, but package with bug is in core repo).

Steps to reproduce:
1. Run 'sudo mousepad' or 'sudo gedit' or etc. in terminal emulator.
2. Try to change any settings and preferences.
3. Console will start spamming with message like:

(mousepad:5866): dconf-WARNING **: failed to commit changes to dconf: Error spawning command line 'dbus-launch --autolaunch=de61eefaab024df39c960ff6b4067f9b --binary-syntax --close-stderr': Child process exited with code 1

I determined that the package must be configured through ./configure with the option --enable-x11-autolaunch, and mousepad or gedit can start and work properly through sudo.

AND

If I will type this command in terminal, it says:

1 dx37@Archey ~ % dbus-launch --autolaunch=de61eefaab024df39c960ff6b4067f9b --binary-syntax --close-stderr
Autolaunch requested, but X11 support not compiled in.
Cannot continue.

how can we fix this? the problem is here since a lot of time how i can see...

Seems to still be prevalent. KDE's partition manager will not work through KDE su. Trying to open any window to browse to a path, for example, throws a dbus error. The problem seems to be packages being built without --enable-x11-autolaunch.

I think this is the guilty PKGBUILD commit: https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/dbus&id=ea3e89691d25e9e700dfd3e9b675c19b55087b6c

I notice that kdesu doesn't work,

for example if I type :
kdesu kate

then there is no window, and no error message, even in dmesg,

it means that I can not run GUI programs in root mode with kdesu,

what is the alternative if kdesu doesn't work ?

@potomac that had nothing to do with this issue. Kate can't be run as root anymore since 17.04 by design

@Antonio Rojas : even with kdesu ?

I tried also to run dolphin with kdesu : it doesn't work,

the fact that there is no error/information message is annoying, the user will think that kdesu is not working

Dolphin can't be run as root anymore either since 17.04
