This might happen to you as it did to me when I upgraded my Ubuntu 13.04 to Ubuntu 13.10, so let me write down the steps that was taken to fix the issue.
Issue: Keyboard not functioning 100% after login. It does not output any characters when typing something on most of the applications.
Description: After the upgrade to 13.10 Saucy Salamander finished on my laptop, the system proceeded to reboot. Everything was normal until I logged in to Ubuntu. Once the desktop finished loading I started Firefox and started typing on the location bar when I noticed that no characters were coming out. I immediately opened Nautilus, started typing something, and also got the same behaviour – there was no output from the keyboard. I tested this with several other applications and the results were mostly the same.
- The keyboard functions normally on the Unity Dash
- Logging into a Guest Session, all keyboard functions are okay.
- Going to another TTY (by pressing key combo, e.g. CTRL + ALT + F3), keyboard works as expected
You need to change the keyboard input method in the System Settings. Follow the steps below.
- Launch System Settings, then search for Language Support. Click on Language Support. (Note: This will launch a new window. There are 2 tabs. Make sure you are on the correct tab as shown in the screenshot below.)
- At the bottom part find “Keyboard input method system”
- Switch to something else that is not currently selected. The options on mine are – “Default”, “IBus” and “None”. (Note: Default was selected in my case. The option that worked for me is None.)
- After making the change, you need to logout and login for the settings to take effect.

Hope this fix works for you as it did for me.
