Hello.

First, please CC me, I do not subscribe this list.

I run VirtualBox (lastes 5.1.X as of ports) on FreeBSD CURRENT and within this
host, I try to run a FreeBSD/NanoBSD appliance. So far, so good. The guest
works well so far, it has port emulators/virtualbox-ose-additions installed and
has

vboxguest_enable="YES"
vboxservice_enable="YES"

enabled in rc.conf.local.

X11 is also up and running and its SCREEN definition is as follows:

Section "Screen"
Identifier "Screen0"
Device "Card-vboxvideo"
Monitor "Monitor0"

SubSection "Display"
Viewport 0 0
#Depth 24
Depth 16
#Modes "1024x768 1366x768 1440x900 1600x900 1920x1200"
Modes "1440x900"
EndSubSection

EndSection

The Guest OS has always a screensize size of 800x600 pixel. The UEFI initial
console shows efifb with 1024x768 pixel, but whenever the graphics starts, it
is reduced to 800x600.

The driver is configured as

Section "Device"
Identifier "Card-vboxvideo"
Driver "vboxvideo"
EndSection

In the lower menu bar, I could, theoretically, switch resolution with menu item
"Virtual screen 1" to a bunch of settings - but only 800x600 is checked and is
selected - nothing else works. I can't select any other resolution!

What is missing here? Something within the driver definition?

I have other guests in the very same VBox, like Windows 7 and I can change
their resolution up to 1920x1080 (I have a screen that is cabapble of
1920x1200).

Thank you very much in advance,

Oliver

Tried, but it doesn't work. The FreeBSD guest window is always stuck with
800x600 pixels :-(

Oh, I ignored the fact you're using UEFI in VBox.
Until a proper KMS driver exists you and I are out of luck.
I always use BIOS firmware for my VBox guests using X11. :-(

All my UEFI VMs run as console-only. Running them in fullscreen at
1280x1024 gives me some comfort.
