I just started experimenting with the Hyper-V of Windows 8 and installed Ubuntu on it. However when I launch it my screen resolution is small.

How can I scale Ubuntu to the resolution of my screen?

Install the Hyper-V Integration Services. This provides better display/input/network integration between the guest and host.

This want help change the screen resolution of Hyper-V. –  Devid Jul 11 at 20:43

In the latest release of Ubuntu, the Hyper-V Integration Services are built into the kernel and won't help. Unfortunately even with windows, hyper-v won't display a larger resolution when accessing it through the virtual machine manager.

Try accessing it through VNC, you will be able to get a better resolution that way.

There is a way to change the screen resolution, just check my answer. VNC and RDP will display in Full Screen but the performance is not good. –  Devid Jul 11 at 20:44

Here is how you can change the resolution of Ubuntu running in Hyper-V:

  • Open the Terminal and type: sudo gedit /etc/default/grub
  • Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT, and add video=hyperv_fb:1920x1080 (or your preferred resolution) in between the quotes (The maximum possible resolution is 1920x1080) like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1920x1080"
  • Save and Exit
  • Run sudo update-grub
  • Restart Hyper-V


Increased display size of Hyper-V to 1680x1050. My Windows 8 display resolution is 1920x1200: change the screen resolution of Hyper-V
