Linux GUI resolution on Hyper-V VM.

Recently I decided to give the Windows virtualization tool Hyper-V a try.
Debian became my OS of choice for the test.
All went well, until I booted into the GUI. The gues OS window was 1/3rd of the whole screen.
So, here is one way to fix it :
Open the file /etc/default/grub with your favorite text editor (vi for example).
Find the line :
GRUB CMDLINE LINUX_DEFAULT="quiet"
and change it to :
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1920x1200"
Just make sure that instead of 1920x1080 you type the desired resolution.
Then run :
sudo update-grub
The change will take effect after you reboot the guest OS.
