You are running by default, the Intel Pstate system in Ubuntu 14.10. To use the older ACPI method, you need to edit the grub file and reboot:
Open a terminal alt+ctrl+t and enter the folowing lines:
sudo cp /etc/default/grub /etc/default/grub.backup
sudo nano /etc/default/grub
In the Nano editor, look for the line beginning with GRUB_CMDLINE_LINUX_DEFAULT At the end of the line add intel_pstate=disable The whole line shoud now look like this
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=disable"
press the keys ctrl+o to write the file, and ctrl+x to exit Nano. Then in the terminal, enter the following command to update Grub
sudo update-grub
You should now reboot your computer, and find that you are able to set the governors as you did in 14.04

According to [http://askubuntu.com/a/544272/142472], 1. there are only two governors available for the new driver, Performance and Powersave, and 2. using the older method is slower – Al F Feb 06 '16 at 12:15
