Only power save and high performance modes available(power save set by default)
It worked perfeclty on Ubuntu 14.04 64-bit, I have this issue on 14.10 64-bit.

[Artem Popov (artfwo)]

Yeah, having the same issue myself on Utopic. Going to look into it next week.

[badmanatee (manateemalo)]

Having same issue. Breaks with kernels >= 3.13.1-031301-generic for me on trusty 64 bit.

Same problem here (Ubuntu 14.10, AMD64).
Here it seems to be related with Intel P-state:
http://www.webupd8.org/2014/04/10-things-to-do-after-installing-ubuntu.html (1.5 section)

Here a benchmark about using or disabling Intel P-state:
http://www.phoronix.com/scan.php?page=article&item=intel_pstate_linux315&num=1

To solve this bug:
gksu gedit /etc/default/grub
than change
GRUB_CMDLINE_LINUX_DEFAULT="quiet ... ..."
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=enable"

Obvoiusly this will disable Intel P-state

[Aaron Hastings (thecosmicfrog)]

Any update on this, Artem? Is there any benefit to running indicator-cpufreq with the Intel P-State driver enabled?

[Daniel Kessel (dkessel)]

Still present in vivid.

[Martin Bednar (martin-bednar)]

It`s also present in 15.04.

[Nicolò Balzarotti (anothersms)]

I added a couple of line for not having the separator with empty CPU freq (hated it)
Line 77:
        freq_selectable = 0
Line 79:
            freq_selectable = 1
Line 89
        if freq_selectable:
            menu.append(Gtk.SeparatorMenuItem())

I still have this problem in 15.04. I tried:

gksu gedit /etc/default/grub
than change
GRUB_CMDLINE_LINUX_DEFAULT="quiet ... ..."
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=enable"

But it didn't have any effect.

[Artem Popov (artfwo)]

Add intel_pstate=disable to grub command line instead. Sorry, there's no proper solution to this problem yet.
