Enabling graphical root login It is highly recommended NOT to allow root to login graphically!In Gnome * Open System --> Administration --> Login Screen Setup * Click on the security tab * Check Allow root loginIn KDE * Open Konqueror and open the /etc/kde3/kdm/ folder * Right click the kdmrc file and then Actions --> 'Edit as root' * On line 246 should be AllowRootLogin=false change it to 'true' * Save and exit.From the Linux Console * Switch to a virtual terminal with Ctrl+Alt+F1 (or F2, F3, ..., F6). You can get back to your X session with Ctrl+Alt+F7. * Log in as yourself. * Become root with "sudo -i". * Start a new X server on display :1 with "startx -- :1". o You can run a different window manager (say, fvwm) with something like "startx fvwm -- :1". o You must use display :1 because the default (display :0) is already being used by you. * Be careful, you're the superuser. Don't forget to logout as soon as you're done, from both X and the console.
