Removing the Black Bar at the Top of the Screen [New Found!]
Solution 1
Use the following setting can solve the problem. (turn off the second monitor)
Solution 2
Sometimes the monitor itself requires some vertical/horizontal alignment via the buttons on the monitor (if it is a separate monitor); often there is an auto adjust button also that should do that for you.
Otherwise if this is not the problem, could you go into the terminal (CTRL + ALT + T
) and type xrandr
then press enter, and post the output here, and also the contents of the file /etc/X11/xorg.conf
to give an idea of the configuration of your displays.
Solution 3
Looks like you'll have to adjust the vertical image offset of your monitor.
Your monitor should have some control buttons with menu options like brightness, contrast and image control among others. Search for the buttons around the edges of your monitor case; in mine it's alongside the power button.
With the menu button, select the image control/image adjust under which you'd find menus like auto adjust, horizontal position, vertical position, ...
Select vertical position and use the menu buttons (+,-) to adjust the vertical offset.
Checking your monitor's manual for details on your monitor settings might help.
Solution 4
Editing the monitor's configuration file may help - In your home directory, run:
gedit .config/monitors.xml
and see if changing the resolution helps.
To find if your graphics card has a driver, run this:
lshw -c display
and look for something like:
configuration: driver=radeon latency=0
This is also possible by running:
lspci -v
and looking for:
Kernel driver in use: radeon
under VGA compatible controller: ...
If you find anything, you could add the info to your question.

[New Found!] 1. When I set to others instead of 1440x900 (16:10) or 1280x800 (16:10) revolutions, the black bar must disappear. 2. When I set to 1440x900 revolution, the black bar must exist.
The display area is not fit to my monitor(1440x900) and there is a black bar at the top of my screen. The bottom of the display area can't be displayed. How can I deal with this problem?
I wonder if the problem come from the lack of display card (MSI R4770 Cyclone) driver but I don't know how to install it. Do I need to install it?
Ubuntu Version : 13.10

gertvdijk almost 11 yearsSo if I understand your question correctly, the workspace on your monitor has an offset downwards resulting in only a portion of the desktop being displayed? Does the resolution setting in Ubuntu match the one of your display (1440x900)? If not, make sure it is set correctly. How do you have your display connected? Analog/VGA/D-SUB cable or digitally (DVI/HDMI/DisplayPort)? If analog, have you tried recalibrating? (usually a button marked "auto" is present on your monitor)

Casper over 10 yearsThe vertical position is already +100. It cannot be adjusted any longer.
-
precise over 10 yearsIf you haven't already, try decreasing the value down from 100. Use

in the menu to decrease the value, probably to 50. -
