The CPU governor is easily controlled in any DE. Ubuntu offers
indicator-cpufreq, which will also work as a tray applet when not
in Unity. I've used it in MATE, IceWM, Cinnamon, even gnome-shell
so it should have no trouble in XFCE either. Many DE's offer their
own CPU governor controls (Cinnamon and MATE both do) but
this one is cross-DE and can be used to set any available CPU
governor as needed.
I normally turn it all the way up for video rendering due to Kdenlive
slowing on the OnDemand governor and use OnDemand for everything
else.
You don't have a newer intel chip then. There is no ondemand... and to
make matters worse there is a powersave, but it is not the same as the
powersave you probably have. My powersave is like your ondemand, but it is
controlled by the CPU, your powersave is probably 800Mhz. My reason for
choosing performance is both the highest speed without over heating as
well as a steady speed as I have found speed changes tend to give xruns at
low latency. However, when I compile Ardour with turbo/Boost turned on I
sit higher (3.4Ghz) but still cool enough with stock cooling than the
design 3.2 Ghz. Ardour build runs 100% on all cores so it makes a good CPU
load test. Anyway, with boost turned on, performance is not a steady
speed, but varies from top design speed to max boost speed depending on
cpu temp and load. So for steady state boost has to be turned off.
There are some other considerations that a simple governor control will
not cover. So we are making a utility to cover all of it.
