Switching UserTo switch to a different user, e.g. student, run To switch to root
Most Linux distribution can be ran in 5 different runlevels. Runlevel 0 and 6 are special, which you can see below.
- 0 - Shutdown
- 1 - Single user mode, without network
- 2 - Multiuser, without NFS (The same as 3, if you do not have networking)
- 3 - Full multiuser mode, with network.
- 4 - Unused
- 5 - X11, graphical mode with network
- 6 - Reboot
The default runlevel is set in /etc/inittab.
How to Switch Runlevels
You can switch the runlevel with init, e.g. init 3. But from the graphical mode, there is also a keyboard shortcut.
ctrl + alt + F1 - for init 1, ctrl + alt + F2 - for init 2, etc.
