I am running 12.04 with the LTS Hardware Enablement Stacks as my VirtualBox host. (I'm using lts-raring and VirtualBox 4.2.20.)
When setting up a new Kubuntu 14.04 guest with Virtual box, upon installing guest additions I saw the warning "Not installing X Window System drivers".
The Kubuntu 14.04 VM runs at a very low resolution (small window). How do I resolve this?
I've gone through the usual steps for setting up the guest additions. Here's the outline:
Devices > Install Guest Additions (Host+D) sudo apt-get install build-essential gcc dkms (and Linux headers, if needed) cd /media/$USER/VBOXADDITIONS_4.2.20_XXXX/ sudo ./VBoxLinuxAdditions.run then reboot the VM
I cannot upgrade VirtualBox because the .deb package tries to uninstall all my LTS Hardware Enablement Stack packages. I've had this happen before and I don't want to risk the damage to my system entailed by that. So I have to stick with VB 4.2.20 on the host.
Update: I just found this: http://xpressubuntu.wordpress.com/2014/02/14/virtualbox-and-the-latest-14-04-display-stuck-at-low-resolution/ Maybe this is related?
