I am running Ubuntu 15.10 in VirtualBox 4.2.34 on a Windows 7 host.

I can't get the desktop to fit the screen.

I installed Guest Additions and allocated enough of video memory, but no dice.

You need install the virtualbox guest additions:

  • In the VM's menu: click "Devices" -> "Insert Guest Additions CD Image" (The guest additions cd image will be mount in your guest's cdrom"
  • Run

    .{path_to_your_CDROM_mount_in_the_GUEST}/VboxLinuxAddition.run

  • Restart your VM

  • Now, with the correct driver installed and loaded: "You have to select "Auto-resize guest display" on "View" menu".

Hope this help!

Before installing the guest addons as described in this answer, I noticed that on a fresh Xubuntu the kernel modules could not been buld because of missing dependencies. So I installed them first using

apt-get install -y gcc make perl

Now I could run VboxLinuxAddition.run from the mounted ISO file. After a reboot, the guest addons were installed. Auto-resize guest display worked, after disabling and re-enabling it in the View menu of the host.

Installing gcc make and perl solved my issue.

sudo apt install gcc make perl

Hope this helps someone.

You have to select "Auto-resize guest display" on "View" menu.

If this doesn't work, then you have done something wrong at Guest Additions installation.
