Hi folks
running Windows 11 HOST and installing a Linux VM (could be Windows - same prob)

The console screen can't be re-sized e.g :

Skjámynd 2022-01-01 143946.png

But in Full size -- it then only has one small display -- I want 1920 X 1080

Works via RDP but I don't really want to use RDP.

Any ideas

Cheers

You can only resize the window of a Hyper-V VM when connected to the guest in an Enhanced session, and that is only available as an option if the guest is a Windows Pro edition, or higher. For a Windows Home or Linux guest the window size (and full screen size) is fixed at the resolution set within the guest OS. Enhanced session is greyed out and the only option in the VM connection window is 'zoom'.

So to get your desired 1920x1080 resolution you'll have to set it within the VM itself. For a Hyper-V Linux VM that requires editing grub.

1) Open Terminal
2) Type: sudo nano /etc/default/grub
3) Find the line starting with GRUB_CMDLINE_LINUX_DEFAULT, and add video=hyperv_fb:[the resolution you want].
So my line ends up looking like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1366x768"
4) Write the changes and quit nano
5) Run: sudo update-grub
6) Reboot the virtual machine

    UPDATE - 11 April 2026: due to lid hinges starting to break up this laptop has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.

    I've now clean installed 25H2 and used Garlin's scripts to update Secure Boot to CA 2023 and revoke the PCA 2011 certificates. It's new role is to test secure boot issues.

    Info for 2021-2026:
    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.

On Ubuntu, you can set up installation to use enhanced mode.

If you cannot use enhanced mode for Debian, you can set it up by making a linux modification.

Thanks Guys

Good info
Funnily enough once I updated DEBIAN with the "development repos" and did apt upgrade I was able to get full 1920 X 1080 resolution.

(I was using KDE desktop BTW on Debian 11).

Another partial solution is in the HYPER-V console view is to select "Manual Zoom" which works reasonably but you can't set it too large as the vertical screen won't show the whole thing -- around 125% is OK.

I'll now mark this as solved.

Networking is now OK too -- Bridged networking is easily enough done so full access to the VM from OUTSIDE the host.

Tunnelling with Putty and 8080 port access works brilliantly too from over the "public" internet,

I like the speed of HYPER-V on Windows -- and the fact that the VM can run in the background so users can logon who don't have Windows user accounts on the Host system.

Thanks "peeps"

Happy new year to all.

Cheers
jimbo
