As I am using a laptop, maximum performance isn’t always what I want.
Sometimes, it’s just better to have not so great but less
battery-demanding performance. It is possible to achieve this by
modifying the CPU governor with ~cpupower~. The [[https://wiki.archlinux.org/title/CPU_frequency_scaling#Scaling_governors][Arch Wiki]] has, as usual,
some really good documentation on this.
The following script asks the user through ~rofi~ which governor to
apply, and it relies on [[#Askpass-d0d7a8c0][~askpass~]] to retrieve the user’s password.
#+begin_src bash
governors=("performance" "powersave" "userspace" "ondemand" "conservative" "schedutil")
governor=$(printf "%s\n" "${governors[@]}" | rofi -dmenu)
sudo -A cpupower frequency-set -g "$governor"
#+end_src
