Xorg "Xorg -configure" Starting and stopping X To start X you can use: startx - terminal command used at level 3; edit /etc/inittab to run default at level 5; xinit - when there is no .xinitrc file; init 5 - to change manually runlevel to 5 (and run display manager); xdm - (X Display Manager) - graphical login manager, which run automatically at boot process when starting Linux at level 5 (there are also external graphical login managers ex. kdm, gdm). To stop X you can use: <CTRL>+<ALT>+<BACKSPACE>; init 3 - at lower level than 5 Linux will stop X-Windows; kill the XFree process. Configuring X To configure X on a system use XF86Setup.
