Hi everybody. Last night I installed Gnome ("pacman -S gnome gnome-extra") everything was OK during the installation process. Then I followed the instructions given in the Gnome-wiki so I edited the /ect/rc.conf in order to start the correct daemons at startup.
Finally I rebooted and I run from the console :
# gnome-session
And it gave me the following warning message:
"(gnome-session: 4597): Gtk-warming: cannot open display:"

Do you know what's going ? Any suggestions please
I used to run XFCE4 with no problems last week.

Thanks in advance

I think you need to create an .xinitrc, with the following line

Thanks redazz, now I can use gnome as a regular user. It's imposible for me to start gnome as root. I think I also need to create a .xinitrc file under root's home directory (it doesn't exist) . What do you think?

You can do the same for root or just simply copy your .xinitrc into roots home (/root). Personally I would avoid using a gui desktop environment as root. If you make any mistakes you can break your system as well as leaving your system vulnerable to crackers.

yeah,.. you are right, I forgot that. Thanks for the help.
