I have installed basic desktop fedora 20 and all the installation done properly my gnome is working well. The touch pad is working here but when I am entering into kde environment I am facing the problem that my touch pad is not working whether when I am connecting the external mouse that works I have also activated all the touch pad checkbox but nothing improved. Then I reset the mouse settings chosen the default settings but nothing changed. But at the first time I entered into kde that time the touch pad worked and after that I have played around the touch pad settings to activate tap click after that touch pad not working still now after resetting the settings also. I don't understand which settings changed wrongly. Is there any recovery exists?
