enforce certain screen resolution

Postby Ecoron » 16. Mar 2020, 04:54

Hi,

I run an Ubuntu Xenial guest on my Arch host (VirtualBox 6.1.4 r 136177) with guest additions installed and would like to be able to reduce the guest monitor resolution to a particular size of 1280x720. Is that possible? How do I do this? I've installed `arandr` on my guest but it does not give that specific resolution as an option...

On my Windows 10 host with an XP guest with Guest Additions installed, I can force the guest to a particular screen size by two ways:

1. in the guest itself with the guest's screen size adjustments.
2. using the Virtualbox window's View Menu > Virtual Screen # > Resize to ##x## choices.

I cannot resize past the host screen size. But once I issue this command on the host and restart the guest:

VBoxManage setextradata global GUI/MaxGuestResolution any

then the host screen size is no limit.
