Mouse and keyboard no longer work after upgrading to 11.04

[Ryan T. Sammartino]

This computer worked perfectly with 10.10.

After upgrading to 11.04 today the mouse and keyboard no longer work. At the login screen, I am unable to do anything: Holding SHIFT or ESC during boot does not bring up the GRUB menu; Ctrl-Alt-Fn does not switch to a terminal; nothing works. Plugging them into different USB slots doesn't work.

However, I am typing this with no problem from the Live CD, so I know it is not a hardware problem. Also the keyboard works fine in the BIOS settings screens. But once the kernel boots, not even the Caps Lock light works.

Comparing (what I believe to be) relevant files between what's on my hard drive and what this Live CD is using reveals no interesting differences.

I have found other reports of this problem (e.g. http://ubuntuforums.org/showthread.php?p=11129795) but did not find any relevant bug reports or solution anywhere.

Here's how I solved this problem:

Boot the 11.04 Live CD.

Switch to a terminal with Ctrl-Alt-F1.

Follow these instructions to mount your HD and get all the necessary /dev entries in a chroot enviornment:

http://www.cyberciti.biz/faq/ubuntu-...e-from-livecd/

Next, edit /etc/default/grub and comment out the line GRUB_HIDDEN_TIMEOUT=0

Run update-grub

Reboot. Now the SHIFT key *will* bring up the grub menu; hold SHIFT after your BIOS POST.

Select an older kernel. For me, 2.6.38-8 worked.

Your keyboard should now work. Go and do an update with the update manager to get the latest kernel.

Edit /etc/default/grub and put the line GRUB_HIDDEN_TIMEOUT=0 back in. Run update-grub. Reboot.

Worked for me. Your mileage may vary.

Hey ryan-sammartino,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

[bugbot (bugbot)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
