Ubuntu screen resolution WITHOUT guest additions

I have red many posts about screen resolutions for Ubuntu as VirtualBox guest. May be I failed to read the good one... So.

I "just" want to make more screen resolutions available WITHOUT installing/modifying anything requiring superuser access in the Ubuntu guest VM (then WITHOUT guest additions).
This requirement is a mandatory security issue for my project.

Thanks in advance

PS: please don't reply anything involving guest additions..

Then you need to adjust the framebuffers of the guest. Since you are negating the guest additions it is all up to you and the guest OS.
Custom xorg.conf would help too depending on the OS. But this is all out of the scope of this forum since it does not deal with VirtualBox.

Thanks for your reply.
I will take a look on this.

By the way, performance issues could explain "install GA" but as performance is not required, I just can't understand why VirtualBox is not in capacity to do what VMware does.

Did you found out how to do it?

I don't find the answer on Google. If you find out please share!
