Rotate your wallpapers over time

[thechitowncubs]

This program was custom made for me by a developer in the nautilus channel. Thanks gicmo!

change-bg rotates your wallpaper (jpg/png) in a gnome enviornment over a specified amount of time.

How do I use this thing? I'm a newbie and I just wanted to have my wallpaper to change over time. I tried using it. Can you give me a HOWTO?

[stalefries]

./change-bg <seconds> <location of wallpapers>
You type that, replacing <seconds> with the amount of seconds between wallpaper switches, then replace <location of wallpapers> with the paths to all of your wallpapers. It's not too hard.

Scratch that. I just got a boat-load of errors.

Package gnome-vfs-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gnome-vfs-2.0.pc'
to the PKG_CONFIG_PATH environment variable

Works fine for me :D.
I will post a full (noob friendly) how to on my blog soon :)

-edit-

Here is a link for those looking for a full tutorial :)

Worked! I missed that part of the dependencies. By the way, would it be possible to add this to some start-up script or other?

Follow the menu: System -> Preferences -> Sessions

[i3dmaster]

very nice! good job man!

[ShiftyPowers]

anyone know an easy way to have this start everytime a gnome session starts? I have it working, which is awesome, but it would be really cool to not have to start terminal every time.

I haven't tested this specific prog but there's another one out there that I use called Wallpaper Tray that works pretty well too.

[lotu5]

this is cool, but for large wallpapers it can be a bit jarring. what would be really awesome would be to implement the kind of fading that mac os x does between desktops...

since this program just tells gnome what to do, it seems like that feature would have to go into the gnome desktop program itself. it looks like gnome pixbufs do have alpha values though, so it shoudl be possible...
