I have used the instructions given in the following link to fix the slow Hyper-V console of a Ubuntu Server box.


I am hoping that there is a way to fix the problem before the install so that the installation routine won't take so long.

Two possible suggestions you could try - during the install you should be given the option to edit your boot line.

Try adding video=vga16fb:off immediately before quiet splash.

Alternatively try the option vga16fb.modeset=0

  • awesome!!! the "vga16fb.modeset=0" option worked!!!

  • I now get the following error message on my new install "gva16fb: Unknown parameter 'modeset'" any suggestions?

  • once you've installed, you'll need to blacklist the vga16fb kernel module as per your linked article - you wont need to use vga16fb.modeset=0 in your grub boot option.

From what I understood in your link, all your did was blacklist the vga16fb module so it won't load at startup. You can dynamically unload a module from the command line using the rmmod command. So if you are using the GUI installed try opening a terminal and running the command:

sudo rmmod vga16fb
  • can this be done from the server install disk, before starting install, so that the installer itself will not be sluggish?
