Comment 7 for bug 1172852

Yes, this is an issue in recovery mode, too. If I hold down Shift while booting, I get the grub menu, in which the keyboard works. I can select recovery mode. However, as soon as it gets to the main menu in recovery mode (the one rendered in ASCII mode, not in X), the keyboard stops working. I have found someone else with the same problem:

I have now had to downgrade to Ubuntu 12.04 so that I can continue working with my computer (this is my work machine).

It is very mysterious to me that this issue does not occur when running from a live USB stick, but does when running from the HDD. It's almost like the presence of the USB key itself prevents the issue with USB input devices from occurring.

Thank you for continuing to explore this issue.
