It's very strange, the computer freeze and I restart it. After the restart I saw 3 icons appeared on the desktop.
I can't delete them! Right click - "Delete" is not active, as well as the keybord. When I opened the Desktop folder they are not there as well !
How can I remove them? How they appeared there when I didn't put them there? Why I don't have rights to delete them when I'm administrator. Why the trash doesn't empty when I click on "Empty trash".
So my questions are: How these icons appeared there? How can I delete them, because I don't want them? Why the Trash can not be empty? Simply doesn't work. Why as admin I don't have the rights to delete that icons? Why these icons doesn't appear in "Desktop folder"?
I removed all programs for tuning and installed again Unity tweak tool and Gnome tweak tool. Again nothing ... I still can't remove that icons and I still can't empty the trash.
