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!!! – Corey Aug 16 '11 at 20:56
I now get the following error message on my new install "gva16fb: Unknown parameter 'modeset'" any suggestions? – Corey Aug 16 '11 at 21:08
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. – fossfreedom Aug 16 '11 at 21:46

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? – Corey Aug 16 '11 at 16:07
