I have used the following command to copy folder containing JPEG and PNG images:

sudo cp -r ~/Downloads/wallpap/ /usr/share/backgrounds/

However the JPEG images turn black while the PNG images are just fine. How do I avoid it?

  • Does this happen if you copy the files elsewhere (using cp and something else), or use the cp command directly on a file? (e.g. sudo cp ~/Downloads/wallpap/file.jpg /usr/share/backgrounds/ ). Also what version of ubuntu are u using? – Wilf Mar 9 '15 at 7:14
  • It happens only when the destination is outside my home directory. I am using ubuntu 14.04 LTS – Palash Sarkar Mar 9 '15 at 10:55

Maybe the files permissions are not correctly set. Run the following to reset permissions to default (644 for files and 755 for directories):

sudo find /usr/share/backgrounds/ -type f -exec chmod 644 {} +
sudo find /usr/share/backgrounds/ -type d -exec chmod 755 {} +
0

if you are copying as the root user (sudo cp -r ~/Downloads/wallpap/ /usr/share/backgrounds/)

then you'll have to change the permissions:

 sudo chown -R username /usr/share/backgrounds/wallpap/

Hope this'll help you
