Nitrogen on the MATE Desktop

Maybe you can help me. I’m running Linux mint mate 18 and very new user. I downloaded nitrogen to change wallpapers on dual screens. Every time I try to change wallpaper, nothing happens. the old wall paper is still there. but when i turn off my system, I see a glimpse of the wallpapers I changed. went on the forums and they told me to run this gsettings set org.mate.background draw-background false
I ran it and nothing happens…usually it would prompt some kind of execution message. went on the forums again and they said it turned off caja background draw. I’m sure it did..but nitrogen still is not changing wallpaper. do u have any suggestions on what to do?..
As you’ve found out, setting up draw-background to false does absolutely nothing of value in this instance. What does however, is a sleep timer and xrefresh -none in a startup script.
Here’s what you’re going to want to do. From Preferences (Preferences>Personal>Startup Applications on Ubuntu MATE), you’ll want to add the following script as follows:
Notice that I added ‘sh’ to the command in Startup Applications. I’ve tested it with and without absolute paths. The above approach works and other approaches don’t.
The script itself needs to contain the following:
#!/bin/bash sleep 30 nitrogen --restore xrefresh -none
The sleep timer allows the desktop to fully load up, then Nitrogen can run and override the desktop drawing with xrefresh. If you have x11-xserver-utils installed, xrefresh is installed already.
Once your nitrogen-fix.sh file is created in your text editor, save it to your home directory using that file name (nitrogen-fix.sh). Now open a terminal and let’s make it executable. You can also do this by right clicking on the file, going to the permissions tab and making it executable. Otherwise, just do this in a terminal:
chmod +x nitrogen-fix.sh
Now that the file is executable, you can test things out by rebooting your PC. Remember, you setup the script to run previously. Just reboot the computer, wait the 30-something seconds post-boot and then you’ll see the desktop revert to the Nitrogen set choices.
