[Bug 1218995] Re: Hyper-V Synthetic Video Frame Buffer Driver not working

Hmm, not sure if this is still an active issue...

but I could finally get it to work by adding the kernel option
video=hyperv_fb:1920x1080    as suggested by codrutoctavian here;
http://forums.opensuse.org/showthread.php/494938-change-suse-resolution-
when-running-in-Hyper-v

For those less familiar with grub (like me)
https://wiki.ubuntu.com/Kernel/KernelBootParameters explains how to add
kernel options.

Frustratingly, even after I reduced my windows resolution back to
1920x1080, the Hyper-v manager still rescaled the vm output to the
original ratio! (this REALLY annoying bc hyper-v can obviously scale
video output and if they scaled up the lower resolution, it would
overcome the postage stamp size vm screen).  Anyway, restarting windows
with 1920x1080 resolution did the trick, with full screen 1920x1080
ubuntu 14.04 running under windows.

Title:
  Hyper-V Synthetic Video Frame Buffer Driver not working

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  Hyper-V Synthetic Video Frame Buffer Driver was added upstream with
  kernel 3.10 (commit:
  http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=68a2d20b79b105f02dcbc52c211d7e62f98996b7)

  I am running Xubuntu 13.10 in a Hyper-V machine on Windows 8 Pro.
  According to the kernel module description the kernel driver should
  allow for FullHD resoltuion and should eleminate the double mouse
  curser. Here neither of that happens though, screen resoltuion is
  limited to 1152x864 like it was with 13.04 before the framebuffer
  driver was added and I still have double mouse cursers.

  lsmod verifies hperv_fb module to be loaded. So there must be
  something which stops the enchansments from working correctly.

  Fixing this bug is important to enable Ubuntu to run in Hyper-V
  environments, which likly to become more important with the includsion
  of Hyper-V in Windows 8.
