Hello everyone!
Sorry for being so OT (again). I had to recompile my own kernel and now
cpufreqd doesn't work. I wonder what I need to enable in the kernel to have
cpufreqd work? What should be the standard cpu frequency scheduler? Which
other schedulers can or must be there? Can I put them into the kernel or will
they have to be modules?
My current kernel config can be found as:

Thanks for reading so far and thanks in advance even more for thinking about
it.
Kind regards
Julien
As I've written to your PM off-list before.
If this is, like it is ...
#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=y
# CONFIG_CPU_FREQ_DEBUG is not set
# CONFIG_CPU_FREQ_STAT is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=y
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=y
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y
... and it is, just run
cpufreq-selector -g performance
when you're making music and run
cpufreq-selector -g ondemand
for office thingies etc.
and don't forget, you might need to push Ctrl + C, if the terminal
should hang.
Don't call this issue OT! It is a PITA and not OT.

PS: Off-list you've written that at the moment you've got a fixed
frequency much below the abilities of your CPU.
You're using Debian, right? So there's a script that always will switch
to ondemand at startup. If you've got a fixed frequency than it must
have to do with the WM/ DE. Are you using a WM/ DE, resp. some special
Braille thingy?

PPS: Did you install a backup of the Linux for your old single core to
the new quad-core and just compiled a new kernel?
2:37 p.m.
Hello!
I copied the config from the old kernel, but I'm not sure cpufreqd did work
correctly there, yet it didn't matter somuch.
I can't do anything with the rest you wrote. There is no cpufreq-selector
and I don't know what WM/ DE should be.
I suppose it is just due to selecting the right modules in the kernel and
knowing which of them to install as modules and which of them can be compiled
into the kernel.
Warm regards
Julien

I read your config and copied the important part to the list, you don't
need a module, all you need is marked with "yes", it's part of your
kernel. WM = Windows Manager, DE = Desktop Environment
For Debian install the package "gnome-applets", even if you shouldn't
use GNOME ;). It's including cpufreq-selector bin, assumed you're using
Debian or a Debian child.

Hello Ralf1
Thanks, I've see the link and the package and thanks for explaning WM/ DE.
Please don't expect me to talk graphic and mouse. :-)
I've also seen the config you've sent back, but I think I either have that
right now or had it before at least. Since all the parts I remember were
marked as YES, which would be my default for trying something.
So is there perhaps a module of that set (cpu frequency scaling) or "acpi",
that I shouldn't have? Is there something, which might block cpufreqd?
Warm regards
Julien
