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 (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 for me on my Win 8.1 host and Ubuntu 14.04 guest. –  Gus Oct 8 at 3:41
    
Did not work for me using Windows 8.1 host and Ubuntu 14.04 LTS. –  Michael Nov 6 at 4:37
    
When using 1920x1080 resolution it work but didn't work with 1920x1200. –  Michael Nov 6 at 4:57
    
@Michael I described above that it won't work if the resolution is bigger than: 1920x1080 –  Devid Nov 6 at 23:49
    
@Devid: I was jut confirming it still doesn't work at 1920x1200. My fault for the misunderstanding. –  Michael Nov 7 at 2:29
