Hi! I have some problems by running programs with the gksu command. The problem is that after gksu prompts for password, I enter the pass, and after I confirm nothing happens. I mean the program that should be started with root privileges just doesn't start. I've already configured the sudoers file and also checked the $DISPLAY variable, it is set to :0.0 . I also tried to run the desired program with the sudo command and I get the following error: "Gtk-WARNING **: cannot open display:". I also tried to run xhost +localhost, it didn't help.
I would appreciate any help I can get. Thanks!

Try:

• Opening your Gnome terminal program.
• Entering su -m and entering your root password.
• Launching your program from that terminal session.

The -m option for su preserves env variables (including DISPLAY).

P.S. In general don't run X apps as root. Why are you doing this?

I've tried with the su -m option, nothing changes: the program just doesn't start from the root console. Without any error message.
PS: I need to start tools like gdmsetup, and everything from the control panel that automatically needs root privileges and asks for root pass. It is really annoying, because I often don't know where the config files are, so that I need these progs.

Hi! As I recently checked the X logfile I found several of the following error messages. They all happened exactly as I tried to get sudo to work with X applications.
Does anyone have an idea what is wrong with my configuration? I know that must be something with the X server don't allow sudo to establish a connection, but I don't know how to change the permissions.
