Ubuntu 14.04 was working fine for a few weeks after installation, detecting USB wireless Microsoft all-in-one keyboard/touchpad. Then it stopped, at least after boot-up.
Keys work before boot-up to input passwords, touchpad moves mouse pointer after boot-up, but clicking is impossible, and no typed keystrokes are registered, so I cannot open a Terminal window.

If I unplug and replug the mouse, it stops working altogether. I've tried other non-wireless mice and Logitech keyboards, but they don't work either.
Starting from Recovery is the same thing. The keyboard works fine before boot-up, so I am trying to get to a Command line from Recovery. Dropping to root shell prompt leaves me with read-only files, and I can't operate commands.
Going to repair broken packages (dpkg), I thought should take me to a Command line, but it always runs through to 98%, then freezes for hours until I have to force restart (holding the power button down, which I know is a bad thing).

What other ways are there to get to a Command line?

  • Did you try pressing Ctrl-Alt-F1 (or F2,F3..,F6) after booting normally?

sorry i confused your question, usually i press ctrl+alt+F1 for login to cli mode, but when your keyboard isn't working how to going there. Hmm, maybe you want to change your first boot to command line mode you can get it here but thats work after boot option menu entered [i mean grub menu].

  • When I press ctrl+alt+F1 as it prompts me to enter passphrase, it sends me to a purple background with a cursor, where i can type commands, but they have no effect. The instructions in the link you gave would work if I could get the computer to detect my ctrl+alt+T command after boot-up, but I cannot. Is there another way?

  • okkay, you can try to boot via usb and try without installations next go to your real ubuntu file system, not file system on your usb boot and then follow that link instructions to change first boot.

  • Was just starting along the same path. Quick question: How do I get to my real Ubuntu file system from the trial version of USB drive Ubuntu?

  • OK, I did that, and it prompted me to enter my passphrase cause my system is encrypted. However, a window popped up saying "Unable to access "128 GB EnCrypted" -- The unlocked device does not have a recognizable file system on it
