Install VirtualBox Additions for an Ubuntu 8.04 Guest | Tombuntu

First you must install VirtualBox guest addition then you simply need to edit this file :
sudo gedit /etc/X11/xorg.conf
Then you make something equivalent to this :
Section "InputDevice"
Identifier "Configured Mouse"
Driver "vboxmouse" <-- this important for Ubuntu 8.04
Option "CorePointer"
EndSection

Section "Device"
Identifier "Configured Video Device"
Driver "vboxvideo" <-- this is important for Ubuntu 8.04
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
SubSection "Display"
Modes "1280x1024" "1024x768" "800x600" "640x480" <-- add the resolution you want
EndSubSection
EndSection

Then save and exit.
Then go in system/preference/screen resolution and select the good one.
That's all.

Have a nice day
