what is backslide fr?

BackSlide is a small add-on for the GNOME desktop environment that automatically rotates your desktop background image on a schedule. Instead of manually changing your wallpaper, you give it a folder or list of images, and it swaps them out at regular intervals, kind of like a slideshow, but for your desktop. The extension lives in the system tray and gives you quick controls to manage it. You can set how often the background changes (the default is every 5 minutes), decide whether it picks images randomly or in order, and add or remove images from your rotation list through a simple preferences window. All the settings sync with your desktop, so your choices stick around even after you restart. People use this if they like variety in their workspace without thinking about it, or if they want to showcase a collection of photos throughout the day. It's especially useful for anyone running GNOME Shell who gets tired of looking at the same background image every time they boot up their Linux computer. Installation is straightforward through the official GNOME extensions store. For those comfortable with command-line tools, you can also build and install it manually by cloning the code, compiling a configuration file, and dropping it into the right folder. The README notes that different versions of GNOME Shell have different branches, so you may need to pick the right one for your setup. One gotcha mentioned in the troubleshooting section is that changing the background sometimes causes the system to freeze briefly on certain setups, but there's a workaround documented in the README.
