Comment 22 for bug 513423

I faced a slow console in a Hyper-V/Ubuntu 10.04 environment. Simply blacklisting fbcon doesn't work indeed. To really prevent fbcon from being loaded, you must configure a placebo modprobe install action. So this is the solution:

--- - 2010-06-17 16:08:53.243630658 +0200
+++ /etc/modprobe.d/blacklist-fbcon.conf 2010-06-17 12:10:02.768999669 +0200
@@ -0,0 +1,2 @@
+install fbcon /bin/false

Don't forget to update your initramfs.
