impossible to launch a program after typing su in a terminal

hello

i have been using xfce for almots 15 yeras now
for the first time a problem which i cannot solve

when i type su to connect as root in a terminal and the launch gedit
i get the following message
that is from SuSE 11.4 and Xfce 4.8
while ti works ok from SuSE 11.3 and Xfce 4 Desktop Environmentversion 4.7.0 (Xfce 4.6)

error occurs while trying to launch any program that way

this way of launching works ok under twm

is anybody having a clue?

Not related to Xfce but rather a change in Gnome's/Gedit's session handling. I think starting like "gedit --sm-client-disable" or maybe --sm-disable will solve the problem.

hello

thanks for this almost instantaneous question

i agree that is a gnome problem not Xfce, but trying to get info from gnome is quite a task!
i must say that this occurs with any gnome application with a similar msg
however your hints do not change anything!!

Re: impossible to launch a program after typing su in a terminal

I use Fedora and have seen this question asked on their help forum several times.  One answer is to use su - instead of simply su.

Re: impossible to launch a program after typing su in a terminal

Although it has been answered, I found that using sudo instead of su for instance, sudo gedit instead of su <enter> <insert password> gedit. I have run into many applications where this is the case and this was my fix.

As Nick stated above it isn't something in Xfce its something in Gnome (perhaps it's policykit or maybe its keychain) but I know that running the commands with sudo prevents this error. I found that even if you have become super user and it still wont launch a program, that simply tacking the sudo in front of  the command will launch the program without having to leave superuser i.e.

$su
password:
#sudo gedit
