Help! I have upgraded from 11.10 to 12.04 but it doesn't pick up the keyboard so I cannot type in my login keyring password to do anything. I have tried a spare USB keyboard but this is not picked up either. Any if I put a USB stick in the menu comes up and I can open and edit a document - keyboard must work! Any ideas? I get an error message - cannot capture your keyboard so cannot get past 'Enter password to unlock your login keyring.'

I have solved both keyboard and networking issues (keyboard not recognized and no network connection) by rolling back to kernel 3.0.0-15-generic-pae.

Just selected 3.0.0-15 in "Previous Linux Versions" section of GRUB menu.

If that works yuo couldalso uninstall newer kernel (sudo apt-get remove and update GRUB (sudo update-grub).

Hope this helps.

Thank you. What Iam getting now is an error message - 'The application Compiz has closed unexpectedly.' The keyboard is now recognised but I just get the desktop background with no icons on it. I can't seem to get any up.How can i get to the GRUB menu? – Nigel Lacey Apr 29 '12 at 10:58
to enter GRUB menu press shift during boot (just after bios screen). I even had to clean up my home directory from profile settigns but still got same error sometimes, but everything works ok. – Eduard Apr 30 '12 at 8:21

I have a similar problem, and can get around it by clicking cancel on the keyring login. Not sure if that helps or not. Unity still not working for me though !!
