Domanda

I would like to set specific "nice" values to several processes in a laptop. For example, I would like the window manager to run at -10, and keep the default at 0.

I know that "renice" can change the niceness of a processes, but this is a-posteriori, and I do not want to "renice" my window manager process every time that I open the computer. Similarly, "limits.conf" allows to specify default niceness for specific users or groups, but not (as far as I know) specific processes.

So my question is whether there is a way to define niceness for concrete processes, without having to change the default for the user and without having to renice the process once it runs.

Soluzione

Use nice(1) e.g.

 nice --5 x-window-manager

or more commonly

 nice make -j 2

You probably need root privileges to give an unnice adjustment (e.g. a negative one which raises the chance of being scheduled). See nice(2).
