I posted the how-to at fedoranews.org too: check it out here!
Before we start you have to install the screensavers package
. If you already have skip installation.
yum install xscreensaver-extras xscreensaver-gl-extras
1st. Create a folder in your home directory and give a name such wallpaper or any other name you want to use.
2nd. Orginize your photos, wallpapers to be used.
3rd. Now, let's remove the fedora images and backgrouds. Open terminal and become root, this command will take you to the /usr/share/backgrounds/images:
Remove the wallpaper:
rm flowers_and_leaves.jpg default.png earth_from_space.jpg stone_bird.jpg tiny_blast_of_red.jpg
Answer yes using "y" only.
[root@localhost images]# rm flowers_and_leaves.jpg default.png earth_from_space.jpg stone_bird.jpg tiny_blast_of_red.jpg
rm: remove regular file `flowers_and_leaves.jpg'? y
rm: remove regular file `default.png'? y
rm: remove regular file `earth_from_space.jpg'? y
rm: remove regular file `stone_bird.jpg'? y
rm: remove regular file `tiny_blast_of_red.jpg'? y
Now go back your your home directory using the cd command.
for example cd imdeemvp which is my home directory.
Now copy your entire photos, pictures, wallpapers from your folder.
cp WallPaper/* /usr/share/backgrounds/images/
4th. Go to Preferences >Screensaver and select the GLSlideshow screensaver and you are done!
