Set 'nice' value to concrete processes, by default <p>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.</p> <p>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.</p> <p>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.</p>
