I'm currently using Ubuntu 18.04.5LTS, and I found that every time I reboot my PC, the brightness automatically goes back to 66%. However, it seems that the volume setting is remembered every time I reboot. Is there any way to make sure that the system remembers the brightness setting before shutting down?

  • On many system, this is remembered. It depends on the graphical card. You will need to provide information about your hardware. Use "edit" to add the information to your question.
