How do I get a larger screen resolution in VirtualBox on Mac OS X?
I fixed the problem by doing:
Turn off 3D Acceleration in the VB settings -- that's why the Guest Additions were locking up after login.
-
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 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.
Restart the VM.
- Now resize the VM window or choose Full Screen mode and it will resize the desktop screen resolution properly.
