Want to run app as root from the terminal? Its a bad idea from a security point of view. You need it for debugging / testing for permission issues? Ok I guess…
Running application from terminal as root will give You errors:
[root@wishmasus andrzejl]# systemsettings
No protocol specified
systemsettings: cannot connect to X server :0[root@wishmasus andrzejl]#
To fix this add these 2 lines (modified properly):
export XAUTHORITY=/home/username/.Xauthority
export $(dbus-launch)
to this file:
/root/.bashrc
Close the terminal, re-open it, use su to gain root’s privilages and try running application again.
IF You don’t want to add this line:
export $(dbus-launch)
You can skip it but then some of the apps will spit out errors:
[root@wishmasus andrzejl]# systemsettings
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
systemsettings(6839): KUniqueApplication: Cannot find the D-Bus session server: “Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.”systemsettings(6838): KUniqueApplication: Pipe closed unexpectedly.
[root@wishmasus andrzejl]#
and You will need to start them with dbus-launch prefix like this:
dbus-launch systemsettings
Cheers.
