set scale factor using vboxmanage

Postby kenbrubaker » 18. May 2016, 04:19

I have not found any reference to "scale factor" or "scaling factor" in the vboxmanage documentation. Can scale factor be set using vboxmanage? How?

Background: I'm trying to use this on Windows using Vagrant in a Vagrantfile, which lets me send commands to vboxmanage.

I don't really think that a scaling factor of 200% needs any special documentation. It's pretty straight forward; make the display twice as big.

Although not explicitly written in the manual, you can issue the command:

    VBoxManage setextradata "<VM_Name>" GUI/ScaleFactor #
where # is your scaling factor. For 100% (no zoom in or out), the scaling factor would be 1. For a 2-times-magnification, make it 2. Anything in between is what you get from the GUI as well. The changes are immediate. If you want to remove the token altogether, just issue the same command but do not include the scaling factor, just leave it empty.

BONUS: I tried a scaling factor of "0.5". It worked flawlessly!!! Nice...

Just for future reference, Vagrant is not supported here. They change too many things and we don't know what...

Works like a charm. Here it is in a Vagrantfile for a scale factor of 125%

Code: Select all   Expand viewCollapse view
    config.vm.provider 'virtualbox' do |vb|
      vb.gui = true
      vb.customize ['setextradata', :id, 'GUI/ScaleFactor', '1.25']
    end

You really should talk to the Hashicorp guys. Community is a terrible thing to waste!

Thanks again.

I personally cannot talk to anyone. I'm a simple user/volunteer with no particular role in the VirtualBox hierarchy. Throughout the years on this forums I've learned that supporting/helping VirtualBox users is quite a job by itself. If you add to the mix 3rd party software that we're not really aware of what it's actually doing to a normal VirtualBox installation, we're going to have way more than our hands full. That's why they have dedicated support forums.
