i am using gnome but how do i install KDE now....and switch between the two?
or use Konstruct
to compile from source.
There used to be an applet to switch between KDE and GNOME but I don't know if it is being developed anymore. Your best bet would be to setup the Login Manager under the KDE Control Center (gdm, the GNOME login manager may already be setup). Then just logout of one enviroment and log into the other.
also how do i set up single click for the desktop? i am too used to the single click in windows so doubleclicking is unnatural for me.
In KDE the single-click option is in the KDE Control Center >Peripherals>Mouse. (labels may be different in Fedora)
and if it is possible can i reconfigure grub so that windoze is the default OS instead of fedora?
change default=0 to default=1
(assuming windows is the second title line in the file)
