I am relatively new to Linux and Ubuntu. I have attached the system monitor to the bar (the upper bar of the screen) and opened the preference to configure this gadget. On the processor tab I see that I can mark the choose 5 colors : user, system, nice, IOwait and idle. I can understand all 4 (I think…) except for "nice". What is this "nice" ? I read this answer and I understand that the superuser can perform tasks with greater priority but , what does it mean if I see it in the system monitor without me running any new nice processes ?

The nice value for the processor is
(from
man top
) A "niced" process is one with a positive nice value. So if the processor's nice value is high, that means it is working with some low priority processes. So this indicator is useful when you see high CPU utilization and you are afraid that this high load will have bad effect on your system:I think this nice value is not too important for a simple user, this is more useful in a server environment.
