I have the exact same problem and I have not found a solution yet. We both did 11.10 to 12.04 upgrades (in my case, I used kubuntu-alternate), we both use logitech unifying receiver/keyboards.
I am able to successfully enter my password and boot into linux when I used a kernel from 11.10 (linux-image-3.0.0-19-generic). I've tried reinstalling the kernels, grub2, and update-initramfs. Wish someone could point me in the right direction. I'm truly lost! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/998651 Title: Unable to enter password to decrypt harddisk after upgrading to ubuntu 12.04 with wireless keyboard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/998651/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
