I had some problems before doing this where xfce won't start (applications started, but no borders and couldn't type anything on the keyboard) and someone told me to use this command
sudo rm -rf /usr/share/xsessions
Now not even Xorg will start. I can do Ctrl + Alt + F1 and use
tty-1 and I tried
apt-get install --reinstall xfce4 but the same problem.
What do you recommend me to do?
