You did not mention what Ubuntu you are using, resp. what startup
process your Ubuntu does use.

If you're using systemd, then use an unit, to

  /lib/systemd/system/

write a file named

  cpu_freq_scaling.service

with this content:

  [Unit]
  Description=cpu_freq_scaling

  [Service]
  Type=oneshot
  ExecStart=/usr/bin/cpufreq-set -u 4.0Ghz
  RemainAfterExit=true

  [Install]
  WantedBy=multi-user.target

then run

  sudo -i
  systemctl start cpu_freq_scaling
  systemctl enable cpu_freq_scaling
