Hyper-v screen resolution in Ubuntu VM with RemoteFX video adapter : <p>I am using Hyper-V for the first time on a Windows 10 installation where I am having some issues with screen resolution in my Ubuntu 18.04 desktop VM.</p>

<p>Guides propose these actions in order to configuration screen resulution for linux based VMs:</p>

<p>Edit grub:</p>

<pre><code>sudo nano /etc/default/grub
</code></pre>

<p>Add video=hyperv_fb:1920x1080:</p>

<pre><code>GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1920x1080"
</code></pre>

<p>Update grub:</p>

<pre><code>sudo update-grub
</code></pre>

<p>And then reboot.</p>

<p>That works just fine until you want to use <strong>RemoteFX 3D Video Adapter</strong> which suddenly changes the screen resolution down to 800x600. Moving windows and browsing the web in the VM seems fine and in Hyper-v Manager under "Physical GPUs" it says "1 virtual machine are currently using this GPU".</p>

<p>I have seen suggestion where installing <strong>linux-image-extra-virtual</strong> package will provide a HyperV display driver but that seems to change nothing. Maybe I am missing something here?</p>

<p>So I am looking for input for how I can be able to use RemoteFX and have a usable resolution in my Ubuntu VM. Suggestions?</p>
