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 '14 at 20:43

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

  • Install linux-image-extras (hyperv-drivers): sudo apt-get install linux-image-extra-virtual
  • 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 (restarting Ubuntu (Linux) might be enough)


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

Worked well on Thinkpad X1 with Windows 10, and Ubuntu LTS 14.04 inside Hyper-V. Resolution is 1920x1080 – mattias Feb 28 at 8:19

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 '14 at 20:44
