GNOME battery level not shown

1

hello, i’m new to nixos and recently installed it first time and now using GNOME.
however, in the right corner of the screen, i usally see my battery life, but instead, i see a power symbol without any battery. why is this?

would be very happy about awnsers :slight_smile:

I think the battery percentage is turned off by default, you can change this by enabling Settings > Power > Show Battery Percentage at the very bottom.

To do this declaratively you can use home-manager:

  dconf = {
    enable = true;
    settings = {
      "/org/gnome/desktop/interface" = {
        show-battery-percentage = true;
      };
    };
  };

first of all i dont use home manager.
also, this setting is already turned on.

i dont see a battery icon anyway, just a power icon.

Can you post a screenshot of this icon?

there should be a battery icon instead of the power icon in right edge

This might be because either your battery is not detected or because the power management service isn’t running or is failing.

  1. To check if the battery is detected, run:
$ upower -e
/org/freedesktop/UPower/devices/battery_BAT0
/org/freedesktop/UPower/devices/line_power_ADP0

You should see something like this.

  1. To check if the power management service is active, run:
$ systemctl status upower
● upower.service - Daemon for power management
     Loaded: loaded (/etc/systemd/system/upower.service; linked; preset: enabled)
     Active: active (running) ...

You should also try getting more information with:

  • journalctl -b 0 | grep -i upower
  • journalctl -xe -u upower

well, i think my battery is detected because htop and gnome settings show the battery percentage. i think that means that it just not shows anything at the bar.

Perhaps it might be better if you ask for help on the Gnome repo or discourse channel for this.
