Can't run "X -configure", "Server is already active" error
Solution 1:
I think you shall have to stop the xserver first. Try this:
- Open a Terminal with CTRL+ALT+F1 and login
-
sudo stop lightdm(or kdm or gdm instead of lightdm if you installed kubuntu or GNOME shell) sudo Xorg -configure-
sudo start lightdm(or kdm or gdm instead of lightdm if you installed kubuntu or GNOME shell)
Solution 2:
run ps auxw |grep X
and kill the process
then run again.
