I've installed Nemo but haven't made it default and I have nothing on my desktop. But sometimes when I boot up I see Computer, Home and Trash icons on my desktop and suddenly Nemo is the default file manager as when I click any of my shortcuts or the new icons on my desktop Nemo appears. When I restart it all returns to normal.
My question is...well... WTF?! I was testing out Nemo and intending to replace Nautilus with something else but this stuff is really weird, can someone tell me what's going on? Should I uninstall Nemo? I'm really new to Ubuntu or Linux in general but I didn't find where those icons would be disabled when I look at my Desktop on Nemo via opening by the shortcut on my Desktop, it shows nothing is there.
When I look for Desktop Icons in Unity Tweak Tool appereantly nothing is there and they don't go away when I tinker with the settings.
But after I restart 1 or 2 times the problem disappers and everything goes back to normal.
So please, somebody help me make some sense out of this. Also could someone tell me how to uninstall a software thoroughly in Ubuntu? It always leaves a lot of junk behind from my experience.
