Slackware Runlevels

Slackware Linux uses runlevel 1 for maintenance, as on other Linux distributions; runlevels 2, 3 and 5 identically configured for a console (with all services active); and runlevel 4 adds the X Window System. Source: http://en.wikipedia.org/wiki/Runlevel#Slackware_Linux To change runlevel, we need to edit inittab file as root. # nano /etc/inittab ... # These are the default runlevels in Slackware: # 0 = halt # 1 = single user mode # 2 = unused (but configured the same as runlevel 3) # 3 = multiuser mode (default Slackware runlevel) # 4 = X11 with KDM/GDM/XDM (session managers) # 5 = unused (but configured the same as runlevel 3) # 6 = reboot # Default runlevel. (Do not set to 0 or 6) id:3:initdefault: ... For graphical login, replace "id:3:initdefault:" with "id:4:initdefault:".
