LINUX Runlevel

From IRIDAS Online Documentation

Overview

After a LINUX installation, sometimes you need to boot into the command line environment to install additional drivers, for example the NVIDIA display driver.

Here are the steps required to boot into the command line environment as opposed to the graphical environment (which is usually the default).

Steps

• Reboot your machine
  
• When the boot manager appears (GRUB), make sure you press a key to enter the detailed menu
  
• Press 'e' to edit
  
• Select your default LINUX boot entry. It usually looks something like this:
  

kernel /boot/vmlinuz-2.6.9-42 ro root=/dev/hda2

• Press 'e' to edit this entry
• Append [SPACE]3 to the command line and press [ENTER]
  

kernel /boot/vmlinuz-2.6.9-42 ro root=/dev/hda2 3

• Press 'b' to boot this entry. LINUX will now boot into Runlevel 3 which is a command line environment
