How to change window manager by editing your home directory?

"/.xinitrc file" allows changing the window manager we want to use when logging into X from that account. The dot in the file name shows you that the file is a hidden file and doesn't show when you do a normal directory listing. For setting a window manager we have to save a command in this file. The syntax of command is: exec windowmanager. After this, save the file. Next time when you run a startx a new window manager will open and become default.

The commands for starting some popular window managers and desktop environments are:

-KDE = startkde

-Gnome = gnome-session

-Blackbox = blackbox

-FVWM = fvwm

-Window Maker = wmaker

-IceWM = icewm
