The screen is too small

I am using Virtual Box 5.0.0(Windows Vista) to run Ubuntu 14.04. The screen is too small (640x480) but the screen can up to 1280x768. How can I resizing it?

You need to install the VirtualBox Guest Additions into Ubuntu. This gives a few benefits, including resizing the Ubuntu screen to match the host window.

Start the VM, then select from the VirtualBox menus:

Devices ⇒ CD/DVD Devices ⇒ VBoxGuestAdditions.iso

Then follow the instructions.

Try this: Setting-->Display-->Scale Factor, change it

I encountered the same problem on my PC recently. This is my solution;

Go to the Ubuntu machine:

Settings ⇒ Display ⇒ Graphics controller ⇒ Choose (VBoxSVGA or VBoxSVGA)

My original settings which caused the problem was VMSVGA.

This solution worked on my PC. I cannot guarantee that it will work on yours.
