hello, I speak slightly English, so I use a translator to understand you better.
I installed ubuntu VBOX 3.1.6 and 9.1. I updated with the ubuntu synaptic.
my computer: amd x2 3 ghz / Asus EN 9800 GT / Asus M3N78 SE

I have a problem with addons guests, when installing the file-VBoxLinuxAdditions x86.run everything goes well to reboot for the mouse, but not for display, when I'm on a window of Windows and I password on the ubuntu image of the old window is still under ubuntu, I move the mouse by clicking on the screen so that the background appears to ubuntu, or pan the window. a problem of refresh or display?

I therefore use other methods. I desinstaille the addons with the remove command. and try an apt-get install dkms before x86. nothing changes
then an apt-get install build essential linux generic header. nothing either

in the display options so you tell me "screen unknown

I do not know what to do thank you for your help, because the mouse works fine in addons invited but always crop the window to see ubuntu display its gets tiring and I must deny myself the addons ...

Let's try this step-by-step then.

• Start the Ubuntu guest. (I am assuming that you have the desktop version).
  Open a terminal.
  Type sudo -i <press enter> (enter your password) <press enter>
  type apt-get update <press enter>
  type apt-get upgrade <press enter>
  after this reboot
  Open the terminal again.
  Type sudo -i <press enter> (enter your password) <press enter>
  Type apt-get install linux-headers-generic <press enter>
  Type apt-get install build-essential <press enter>
  Now look up at the top left of the VBox window and click devices then click install guest additions.
  If they do not show on the desktop then click devices and unmount CD, then click install guest additions again.
  At this point they should be on your desktop. Dbl click to open the CD.
  Look for the Linux Guess Additions that fits you install. More than likely the VBoxLinuxAdditions-x86.run
  Position the terminal windows and the opened file system to where you can see them both.
  Click and drag the right additions file and drop it on the terminal window.
  Click on the terminal window to get focus and hit enter.
  Watch for any errors that show and when they are complete reboot.
  Let me know if you encounter any errors. If all is well you use the click drag to make the window bigger or use the host+F toggle to go in and out of full screen
