How-to: Install Ubuntu 14.10 in VirtualBox
Oh. Here we go again. It's the graphics. It doesn't appear to set the right graphics mode when the 14.10 ISO image fires into the installer.
But we can fix that. Again.
My Debian 7 host has the latest version of VirtualBox (4.3.18 r96516) running 14.04 in a virtual machine, so I'm going to re-use that VM for 14.10.
The mouse pointer shows up full height and moves around, so I know the VM hasn't crashed.
The suggested solution on the web is to switch to a tty terminal session and back again, to force-refresh the Guest graphics mode. Normally I'd do this using CTRL+ALT+F1 to go to tty1, then CTRL+ALT+F7 to switch back to the GUI; but you will probably find this is key combination is received by the Host and not the Guest.
So with window focus on the Guest VM, the correct key combination to switch to Guest tty1 is:
At this point you sould drop into the tty terminal window:
Welcome to Ubuntu 14.10 (GNU/Linux 3.16.0-23-generic i686)
Note: I have right CTRL setup as the default escape focus key for VirtualBox VM's.
Beyond that, the installer should run fine through to a clean desktop, albeit in a limited display resolution.
Next, run Software Updater to apply the latest patches, then from the VirtualBox Devices menu, select Insert VirtualBox Guest Additions CD and the Guest Additions installer should prompt you to install the latest guest drivers. The VirtualBox guest display driver should select something more useful, although getting optimum settings is something you may need to play around with. RC
