I'm trying to install forticlient on fedora 14 for vpn access, and I get the following error when I run it for the first time:

No protocol specified
Error: Unable to initialize gtk, is DISPLAY set properly?

Any ideas what could be causing this problem?

Everything points to something wrong with XOrg.

  • No protocol specified is an Xlib error.
  • gtk is the GIMP Toolkit, and it depends on Xlib.
  • DISPLAY is an environment variable used by Xlib to determine your display.

Do you have XOrg running? Is there something wrong with it? Can you not start other GTK apps?
