Try System Settings - Display and Monitor - Multiple Monitors.
The setting Show Unmanaged Windows on allows you to select a display or use the display the mouse pointer is on.
I had this problem but only when I first started a session, anything I ran would always initially open on the second screen (which is a TV and usually turned off)
If you're having ...

Similar to Robin Green's answer, but this does not require a terminal window to be open already. Instead, specify the display in which to start kwin from tty1. Hence,
Press Ctrl+Alt+F1 to access a terminal. Log in.
Type killall kwin. Then, type in DISPLAY=:0 kwin.
Press Ctrl+Alt+F7 to change back to your primary display.

I've been using Unity-2D with KWin for about two weeks now. In the login screen, choose Unity-2D as your session type. Install the kde-window-manager package to get kwin. Then fire up a terminal and run kwin --replace &!. You'll probably want the systemsettings and kde-config-gtk packages for configuration.

As @warwaruk said, you already have KWin. "Plasma" is the name of the desktop environment that uses KWin, so you should select Plasma when you log in.
You said "I have installed KDE by command sudo apt-get install kde-window-manager". If you want the full KDE environment, you should install kubuntu-desktop or at least kde-workspace, to be sure you're not ...

Press Ctrl+Alt+F1. Log in. Type killall kwin.
Press Ctrl+Alt+F7.
Quit all open applications until a terminal becomes visible. Hover the mouse over the terminal application. Type kwin &.
What's that, no terminal application open? Tough - you'll just have to reboot.

kwin does have a DBUS interface, but it doesn't do what you're describing.
To take a look at the calls that are available to you, run qdbusviewer (which be available in your distro's repository), choose the Session Bus tab, and search for kwin in the search box. From there, choose org.kde.KWin on the left panel, and on the right panel, you'l see KWin -> ...

The AMD Catalyst software has an option to reduce tearing.
Open a terminal and type gksudo amdcccle, then find the section for reducing tearing and check the option.
Additionally, I should mention that I had some tearing issues with VLC and Totem a while ago (before the 13.1 driver was released), but using smplayer instead of VLC dramatically improved my ...

I have the same problem. Nvidia 660ti KDE 4.8 and 304 drivers.
I ran some tests with different configurations (Nvidia settings and KWin) and it is related to the PowerMizer settings. On adaptive, I get tearing both on desktop and video (both with VDPAU and without). On max performance, tearing is gone.
Hope it helps.
