Fullscreen of Fedora10 installed on Vista using VirtualBox

Installing Fedora10 on Windows Vista using Virtual Box was very straight forward. I used a live disk or the iso initially and once the virtual machine booted up, I used the option of install to hard disk to avoid using the iso or the Live CD. The complex issue was that the screen size is too small i.e. the highest available resolution was 800 x 600. My Vista is using 1280 x 800, hence the Fedora on Virtual Box looked very small. I was able to make it full screen by following certain steps mentioned as below:
  • Run the Virtual Machine installed using VirtualBox. Go to the Devices menu and select the "Install Guest Addons . . ." option. Reboot the machine.
  • When the virtual machine is shutdown, you should be able to see that in the settings "CD/DVD-ROM" section will be configured for the "VBoxGuestAdditions.iso".
  • On the Virtual Machine startup, you shall be able to see this iso mounted and have icon on the desktop.
  • Before these Addons can be installed certain dependencies like make, gcc, kernel-headers and kernel-devel needs to be installed. These can be done using the following commands:
      • #] yum install make
      • #] yum install gcc-c++
      • #] yum install kernel-headers
      • #] yum install kernel-devel
  • When the dependencies are installed, we proceed installing the addons
      • #] cd /media/VBOXADDITIONS_2.0.6-39755/
      • #] sh ./
  • Reboot the Virtual Machine. Now fire the commands to get the Display in the System > Administration menu.
      • #] yum install system-config-display
  • Now you can open the System > Administration > Display window. In the Hardware tab, select the VBoxVideo drivers in the Video Card configuration. Press OK two times and reboot the machine.
  • On restart, again open the Display window. If the desired resolution is not being displayed then you have to manually modify the /etc/X11/xorg.conf file.
  • Open the /etc/X11/xorg.conf file . Modify the Section "Screen". You need to add the Modes.
  •       Section "Screen"
             Identifier "Screen0"
             Device     "Videocard0"
             Monitor    "Monitor0"
             DefaultDepth     24
             SubSection "Display"
                 Viewport   0 0
                 Depth     24
                 Modes "1024x768"
  • Reboot the machine. On restart, you shall see the Virtual Machine will start with the new resolution. To have full screen press the host + F keys. By default the host key for Virtual Box is Right Control key.
