I recently installed a program called nemo which is a file manager meant to replace the default GNOME files manager. I installed it using the tutorial and it said that if I wanted to remove the desktop overlay after using nemo, I would type the command nemo --no-desktop. For some reason however whenever I log out and log back in I get a transparent desktop window which I can not remove by clicking the close button. Is there a command or anything that can fix this? If not then I am also not sure how to uninstall the nemo program in order to keep the GNOME files manager. I did not install through the software center.
I got the tutorial from here (scroll down to where it shows nemo).
