I have recently installed KDE, xfce,I already had gnome 3 classic and obviously unity. But now I cant choose between them because the ok button is hidden off the screen. What should I do?

What OK button? Unless you changed your DM (login screen) you should be able to select your desktop environment using the Ubuntu logo that appears next to your user name before you log in.

Is your login screen like this? Can you see the Ubuntu logo next to the user name?:

any time the ok button is off screen you can push and hold the Alt key while dragging the window up till you see the ok button.

Will that work with the login screen?
