I have searched all over to try and solve this and so far I came out empty handed. Basically, I have Windows 10 PRO and installed Hyper-V since VirtualBox just doesn't want to work even with all the necessary modules installed.
So my problem is that after installing Hyper-V I tried to install a VM quickly (Ubuntu 18.04) and my resolution was locked to 1152x800 or something like that. I did turn on all the prerequisites :
1) Enhanced Session Mode Policy 2) Enhanced Session Mode
and I still have Enhanced Session greyed out. This also happens with a Windows 10 Home VM I installed. Just for the record, last time I used Hyper-V I There was this "Remote FX" plugin that is no longer supported so. Anyways does anyone have any idea how to solve this? As far as I know I am up to date.
