can anybody help with this issue. I searched for information but nothing.
Any sudo command I execute, I get:
Error no display name and no $DISPLAY environment variable.
I saw in information center -> server X that the name value is “:0”. Is it correct?
I tried to set the environment variable in the /etc/environment to DISPLAY=localhost:0 but without success.
If it could be of some help, I forgot to mention that I run openSUSE with VirtualBox.
Thanks a lot.
