Installing Ubuntu 10.04 on Windows 2008 R2 Hyper-V

You can either wait for a distro-integrated kernel to include it, wait for someone in the community to build an appropriate kernel package (which probably won't take too long), or patch and build a kernel yourself. Unless you're familiar with the procedures for building a kernel and applying kernel patches (given that there'll likely be significant changes between the Ubuntu-released kernel and the bleeding edge kernel these patches are targeted at), I'd leave it alone and wait for someone else to do it. It won't be a trivial operation.

To work around this issue, you need to disable the frame buffer module: edit /etc/modprobe.d/blacklist-framebuffer.conf and add the following line:

blacklist vga16fb

Reboot and the console should be fine.

This solved the problem for me. I learned about it here: http://solyaris.wordpress.com/2010/05/01/ubuntu-10-04-on-intel-driver-and-server-frame-buffer/
