This simple widget shows the status of your video graphics card using the "prime-select" command and lets you switch between your Nvidia card and your intel video card. Also, it gives you the option to see what version of Nvidia drivers you have and a quick shortcut to open nvidia-settings from the System Tray.
For this widget to work like a charm, you need to have installed "libnotify-tools" (This is required if you want to be notified when you switch video cards) and you need to have the Nvidia drivers installed and the switch "prime-select nvidia" and "prime-select intel" working properly.
You can customize the names and models of the video cards in settings.
This widget works on dark and light themes.
