Configuring on FreeBSD guests running in VirtualBox

Configuring X11 is more or less a dark art, and you must almost be a wizard of the Slytherine House to get modern 1.14.7 working on a FreeBSD guest in VirtualBox.

Nonetheless, through lots of experimentation this evening, have I finally arrived at this configuration file:

Section "InputClass"
  Identifier      "Keyboard Defaults"
  Driver          "keyboard"
  MatchIsKeyboard "on"
  Option          "XkbLayout" "no"

Section "InputClass"
  Identifier      "Mouse Defaults"
  Driver          "mouse"
  MatchIsPointer  "on"

Section "InputDevice"
  Identifier      "Mouse0"
  Driver          "vboxmouse"
  Option          "CorePointer" "on"

Somehow, you need both the InputClass and the InputDevice sections to get the mouse working as it did in previous versions of The option CorePointer is also key to the success.

Not only have I achieved Norwegian keyboard layout, the mouse sends its events to the X Server, and the mouse cursor is able to leave the FreeBSD guest whenever I want.

Maybe I’m the next Voldemort afterall. :P

Local slave port for emulators/virtualbox-ose-additions without OpenGL and X11

I have a bunch of FreeBSD VMs running in VirtualBox. They all share a number of virtual harddrives, and among them are a virtual harddrive with the common contents of /var/db/ports.

My ports configuration of emulators/virtualbox-ose-additions have the OPENGL and X11 options set. This is useless on some of my simpler VMs, as those VMs have no need for any X11 ports, but they could sure benefit from having the VirtualBox additions installed. These simpler VMs are usually used only to test ZFS in FreeBSD in various configurations.

I could juggle the settings for emulators/virtualbox-ose-additions for each time I’m updating the VirtualBox additions port on my VMs, but I decided to create a local slave port disabling the OPENGL and X11 options. Maybe this port, with the necessary tweaking, could sit among its siblings in the official emulators category.


MASTERDIR=	${.CURDIR}/../../emulators/virtualbox-ose-additions
.include "${MASTERDIR}/Makefile"


COMMENT=	VirtualBox additions for FreeBSD guests without OPENGL and X11


PKGNAMESUFFIX=	-additions-nox11



For now you must copy the /var/db/ports/local_virtualbox-ose-additions-additions-nox11/options file to /var/db/ports/emulators_virtualbox-ose-additions-additions-nox11/options, or else dialog4ports(1) will keep nagging you until kingdom come.

I guess this problem stems from early processing of as done by the master Makefile at a time when the CATEGORIES variable was set to emulators.


I’m probably not paying enough attention to new developments in FreeBSD after all. After updating the installed ports in my VMs running base/head and base/stable/10, X11 stopped working. It turns out the new version of requires KMS and what not in the kernel. This doesn’t fare well with VMs running inside VirtualBox.

The solution? Place


in the /etc/make.conf file and recompile everything, or at least recompile everything belonging to the subsystem. I opted for the former, spending roughly five hours recompiling 443 ports. :-/

The VMs running base/stable/8 and base/stable/9 hasn’t been affected yet, but I figured it’s best to play safe and I amended the aforementioned line in the /etc/make.conf file on those VMs.
