Hi everyone i wanted to share a script which displays photos in screensaver style. i hate how xscreensaver has parts of the screen in black, especially with portray photos. So i wrote a script which fills the background, blurs the image, and then places the photo in perspective over the top of that. Looks very nice!

The script is configurable, and will install itself when run for the first time. (You will need sudo rights to install its dependencies if you haven't already got them installed. Run the screensaver2.sh file in the DefaultDirPath directory ($HOME"/Scripts/screensaverfiles) after installation.) The screensaver detects full screen and/or web videos or video players playing and has the option to blank screen at a set time.

The script should run on any KDE, Unity or LXQt desktops, but should be easily configurable to run on other desktop flavours.

[code]
#!/usr/bin/bash
#run this script to install it in the DefaultDirPath directory.
#After installing run screensaver2.sh in the DefaultDirPath directory.
#This slideshow aims at filling the screen keeping the images in ratio by blurring the background with the same image.
# When an image is displayed it is removed from the photo list. When the photo list runs out a new one will be automatically generated.
#Ubuntu based distros with KDE, Unity or LXQt Desktops are supported by default.

Yeah, I can set a screensaver just fine, it's just creating the slideshow that is the problem for me. Thank you for the article!
