linux operating state

[Mike_robbin]

can anyone help me with changing the default run level in Linux as am beginner for using this OS.

"runlevels" are a SysV init concept and not still applicable to systemd Linux systems such as Ubuntu/Mint (and most anything else). You will want to specify what you actually want to do.

until topic is on snooze it can be just mentioned that there are systemD compatibility targets runlevel2.target, runlevel3.target, runlevel4.target, runlevel5.target called when appropriate for SysV runlevel 2-5 requests. For runlevel1 it is possible to use systemd.unit=rescue.target or its alias systemd.unit=runlevel1.target.

If, however, OP now feels that an answer to his question, you not I will now get to deal with it undoubtedly not being so

In relation to this everyone using anything like that in Ubuntu is on one's own In Debian it is really maintained and rescue.target even integrated in the installation DVD. I have a successful session with it recently after 'accidentally' destroying with my own hands my encrypted system, seemingly beyond any hope to boot it ever again. Just need to cool down enough before that.

The question I have is why would you want to change the default run level?

I'm wondering the same thing. I don't think I even knew what a 'runlevel' was when I was a beginner to Linux.
