no mouse after install

[Thomas Gill]

You can try a ctrl+alt+<backspace>to get to command line and then try
sudo dpkg-reconfigure xserver-xfree then look in nano
-w /etc/X11/XF86Config ctrl o to save plus enter then ctrl x to exit It
should look somthing like this;
Section "InputDevice"
	Identifier	"Configured Mouse"
	Driver		"mouse"
	Option		"CorePointer"
	Option		"Device"		"/dev/input/mice"
	Option		"Protocol"		"ImPS/2"
	Option		"ZAxisMapping"		"4 5"
EndS



I tried the previous advice, but response to sudo command was: xserver-xfree not installed

Do I have to be logged in as root, and if so, what is root password??. Don't recall being prompted for that during the installation. 

Any responses, please bear in mind I have NO experience with Linux command line.  Original post described how I had no mouse function after installation, and had same problem with a Fedora install. Thanks.
