Menu
If you install Ubuntu 14.04 inside a Hyper-V virtual machine – you automatically get all the integration components and virtualized drivers. Including the Hyper-V video driver. However, if you try to change the screen resolution inside your virtual machine you will notice something odd:
Dec 21, 2016 - When working with headless devices, video card sometimes only outputs a minimal resolution. That's the reason why TeamViewer is showing.
There is only one choice!
Luckily, you can change the screen resolution. Just not here. What you need to do is:
- Open Terminal
- Type: sudo vi /etc/default/grub
- Find the line starting with
GRUB_CMDLINE_LINUX_DEFAULT
, and addvideo=hyperv_fb:[the resolution you want]. The resolution I want is 1280x720. So my line ends up looking like this:
GRUB_CMDLINE_LINUX_DEFAULT='quiet splash video=hyperv_fb:1280x720'
Write the changes and quit vi.
Run: sudo update-grub
Reboot the virtual machine
Now you will get the resolution that you want!

I am fresh new on linux and tring to connect on a TV
http://www.cnet.com/products/samsung-ln-s325d/specs/ using DVI.
Problem: The screen resolution isn't good :(
I've tried many things with the xrandr command, but in the end, the new mode just doesn't work (black screen).

Here is the terminal:
From there,
or system settings > Display >1368x768 (16:9)
just gives me a black screen saying the mode is not available
I have tried many other resolutions, but any custom resolutions do that.
Anyone have an idea?thanks! :)
