System/software info

  • Ubuntu 20.04
  • Kernel version 5.4.0-29
  • Openrazer version 2.8.0~1~524
  • Polychromatic version 0.3.12

Updated to 5.4.0-29 today, and with this update, my wireless mouse's battery percentage is now periodically displayed as a notification on the top of my screen. At first, I found this very useful, as I thought the notifications were only for low battery percentage, however, they are showing up seemingly every time that the percentage changes [Edit: they also just happen on a random interval apparently, even when the percentage doesn't chane], see the screenshot below:

(Apologies for the image quality, couldn't find a great way to snap a picture of the notification dialog)

I have two questions branching from this.

  1. What software is displaying this notification?
  2. How can I change when it is displayed?

The battery notification feature is part of the OpenRazer daemon itself -- Polychromatic has no control over it.

To disable it, there's an option inside ~/.config/openrazer/razer.conf in your home directory:

# Mouse battery notifier
mouse_battery_notifier = True

To change when it sends a notification, edit /usr/lib/python3/dist-packages/openrazer_daemon/misc/battery_notifier.py as root and set the interval at line 16:


(In seconds, so 10 minutes)

(Also note that editing this file will cause it to get overwritten when OpenRazer updates)
