I am running the new Mac Air 13" with OS X 10.8.2. I then downloaded the latest VirtualBox 4.2.6. Then, I installed Ubuntu 10.04 into the VM.

First off, after I installed the VirtualBox Guest Additions and restarted the VM, the Ubuntu desktop froze after the GDM login and I had to delete the VBoxGuestAdditions folders out of /opt and /usr/lib to get back to normal again.

Second, I go to Ubuntu's System > Preferences > Monitors and try to change the settings, and there's nothing higher than 800x600. I then tried the VirtualBox various View menu settings and tried again in Ubuntu's System > Preferences > Monitors and I'm still stuck.

I fixed the problem by doing:

  1. Turn off 3D Acceleration in the VB settings -- that's why the Guest Additions were locking up after login.

  2. Run this in the terminal of your ubuntu virtual machine, not the host OS: 

    apt-get update  
apt-get upgrade  
apt-get install dkms  
apt-get install build-essential

  3. Go to the Devices menu and tell it to install the Guest Additions. A new CDROM will appear on the desktop. Rightclick and choose the Autorun.

  4. Restart the VM.

  5. Now resize the VM window or choose Full Screen mode and it will resize the desktop screen resolution properly.
