One way to work around this is to use: sudo -v If it does, you won't see the password prompt. To prevent this, you might think you could instead launch the graphical root terminal with: sudo -H gnome-terminal &īut this will only work if sudo doesn't have to prompt for a password. This is because the root graphical terminal is sent SIGHUP when the terminal that owns it is exited. then the root graphical terminal quits as well.

Running gnome-terminal as root without a controlling non-root terminal: Since you have the gksu package installed, you can run gnome-terminal as root with either of: gksu gnome-terminal I present two ways: with gksu/ gksdo, and with the sudo command. You'll have a root shell in which commands you enter will be run as root (without having to precede them with sudo).īut if you really want to run the graphical terminal emulator application as root, read on.
