I am trying to set up an Ubuntu guest on a Hyper-V server. I am relatively new to Linux so please bear with me, the VM is a test machine to get the hang of things and give Ubuntu a try. One of the new features of Server 2012 R2 is the improved display capabilities as mentioned here at blogs.technet.com
I don't think I am alone in finding this doesn't "just work". Some advice found online suggests updating the kernel, which I have done to 3.11.6 as described in one post, and to the latest 3.12.1. In both cases I could only see resolutions listed under the display options up to
1152x864, which is what Linux has always been limited to under Hyper-V.
Another clue was found in the next link (in Japanese) - the poster has added
/boot/grub2/grub.cfg. When I went to repeat this I noted the message about not editing
/boot/grub2/grub.cfg directly so I have added the line in
This has not given the option for the full
1920x1080 resolution either, and at this point I have run out of things to try and would not know if this is now a Hyper-V issue or something more fundamental and this would not have worked on a physical or other hypervisor machine.
If anyone can shed some light I would be most grateful.
