Laptop battery tool#
In the early days, when I switched from Windows to Linux on my laptop, I wasn’t able to manually monitor my laptop fan profiles for temperature issues.
So, I found these tools on the AUR: chillspot and slimbookbattery
Since I had just recently started using Hyprland and chillspot required root privileges, I was getting an error.
(chillspot:176865): Gtk-CRITICAL **: 00:00:23.393: gtk_icon_theme_get_for_display: assertion 'GDK_IS_DISPLAY (display)' failed
(chillspot:176865): Gtk-CRITICAL **: 00:00:23.393: gtk_icon_theme_add_resource_path: assertion 'GTK_IS_ICON_THEME (self)' failed

(chillspot:176865): Gtk-CRITICAL **: 00:00:23.394: gtk_icon_theme_add_resource_path: assertion 'GTK_IS_ICON_THEME (self)' failed
RuntimeError: Gtk couldn't be initialized. Use Gtk.init_check() if you want to handle this case.
My guess is that it was due to chillspot bring an x11 application, it won’t run on Wayland.
My solution:#
sudo -E chillspot
The -E (or --preserve-env) option preserves the user’s environment when running the command. This means that if your user session has access to an X11 display, using sudo -E might pass these environment variables (such as DISPLAY and XAUTHORITY) to the chillspot application running as root, potentially solving the issue.
Conclusion#
While sudo -E chillspot might temporarily solve the problem by ensuring environment variables are preserved, it’s not the most secure or recommended solution.
At the end, it worked out for my usecase.
