Windows 8, Fedora 19 OS Hyper-V Virtual Machine

Question

I installed Fedora 19 in windows 8 hyper-v and its working fine but there is one small problem with the display setting, as fedora 19 display setting not providing 1366x768, but i need to set the display to 1366x768 to view full screen, so any suggestions??

Answer 1

• Open a Terminal (Ctrl-Alt-T)

• Run

    sudo vi /etc/default/grub 
  

• Find the line starting with GRUB_CMDLINE_LINUX, and add

    video=hyperv_fb:[the resolution you want]
  

If the resolution I want is 1280×720 then my line ends up looking like this:

    GRUB_CMDLINE_LINUX="… quiet splash video=hyperv_fb:1280×720"

• Write the changes and quit vi by hitting ESC and typing

    :wq
  

• Run:

    sudo grub2-mkconfig -o /boot/grub2/grub.cfg
  

  or when installed in EFI mode

    sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
  

• Reboot the virtual machine

Answer 2

(Note: this is just an over-sized reply.)

I'm using Windows 10 and Fedora 26. Basically what Daniel said still holds, with some modifications:

1. The file /boot/grub2/grub.cfg doesn't exist on fresh install Fedora 26, and creating the file doesn't affect booting parameters at all (verified with /proc/cmdline). The correct file is /boot/efi/EFI/fedora/grub.cfg (I get the path from Fedora Wiki).

2. Not every resolution is supported: 1920x1080 is, 2560x1080 is not. Unsupported resolution is simply ignored. I ended up setting it 1920 although my monitor is 2560.

And finally an advice: back up everything you edit. You'll need it some day.

Update: still works in Fedora 27.
