After upgrading to Ubuntu 14.04 a strange error occurred: keystroke on c has no effect, whereas a longer stroke gives a lot of c's (as expected).

The error is reproducible, but appears in Unity only, not in Gnome 3.10 which is installed as well. Key c still works well at the login prompt. Changing the keyboard layout (from German to English) has no effect. So it shouldn't be a hardware error, nor an error of the keyboard layout. But what else could it be? As far as I mentioned, there are no other keys affected.

Does anyone have a clue?

After checking user275435-comment, I found a solution: I looked through all shortcuts and disabled (press backspace) all with a hexcode, e.g. 0xa1. Now the c-key works again.

Finally, I found a solution: As only Unity was affected, I came across this solution: change dash lens hotkey

But since lenses are scopes now, I edited file /usr/share/unity/scopes/photos.scope instead (as root): Change

Shortcut=c

to

Shortcut=

and for security, add

ShowEntry=false

Then restart Unity and log out or restart computer.

Additionally I removed all the lenses/scopes I never use: remove unity lenses

Do the logout/restart thing again and, voilà: Key c is working again!

I had the same problem after upgrade to 14.04 on the unity desktop, the problem was the program touchpad-indicator. This has a shortcuts created under "All Settings - Keyboard - did own shortcuts"

  • Thank you. But unfortunately I don't have that program installed. And "settings > keyboard > own shortcuts" is empty. – kroeja Apr 28 '14 at 19:01
