Comment 48 for bug 559163

Well, in the land of the weird, home of the strange, solving this problem would seem to invoke others, e.g., no sound AGAIN and an inability to shutdown, either from the desktop or with 'sudo shutdown now'. So I erase the nomodeset and ran update-grub again. After forcibly shutting off the laptop and re-starting, there was sound and I was able to shutdown normally.
