grub suddenly unable to get keystrokes from wireless keyboard and mouse

[Gordon Fitch]

Problem appeared after automatic update of version 12.04, (12.04.5) and also after trying to update to 14.04. Keyboard, mouse work OK with previous versions and LiveCD of 12.04.1. In 12.04, loader presented menu from which selection could not be made with either mouse or keyboard and did not time out. In 14.04, could not select from menu but menu timed out.

Substituting old-style keyboard and USB mouse caused problem to disappear (thus far). Boot is normal, computer is now running normally.

Ubuntu versions: see above.

Wireless keyboard is Logitech Y-RAK73. No legible information on mouse or receiver.

Attempted to use Apport, but it crashed.

When you get the working menu in 12.04, are you sure it is grub and not the syslinux menu? What choices are on the menu? Can you press 'C' and get the grub command line? Are the choices the same on 14.04?

[Gordon Fitch (gcf)]

The menu I saw offered different versions of the operating system, one per line. Since both the keyboard and the mouse were apparently not effective, pressing 'C' would presumably have no effect. The choices were different after I installed 14.04 and tried that, but the failure to receive anything from the mouse or keyboard was the same.

I was asking about when you boot the 12.04 live cd that you mentioned did not have the problem.

[Gordon Fitch (gcf)]

I was not able to obtain a command line from the 12.04 LiveCD.
It was made on Oct. 3, 2012, probably right after installing
12.04 for the first time, if it makes any difference. Can I
get the information by reading the disk?

Gordon Fitch, could you please boot into the live environment via http://cdimage.ubuntu.com/daily-live/current/ and execute the following via a terminal:
apport-collect 1398035

Given this happened after upgrading 12.04.1 to 12.04.5 (which only changes kernel and xorg bits, no userspace changes) the root cause would appear not to be a grub2 but kernel space.
