I don't know what I did but now some keys from the keyboard are not typing the corresponding letter but move the cursor instead. The expected letter is typed if I press the fn key at the same time. With the shift key pressed the funny keys type numbers.

I've read about a similar issue where the numlock key was activated. There is no numlock on this keyboard. I've installed numlockx and run 'numlockx off' : no change! With 'numlockx on' : the funny keys type numbers.

I've tried rebooting off course: nope...

Here an image of the keyboard : keyboard

  • It is not clear to me from your highlighting, what you have run in the terminal. You should not run run 'numlockx off', instead run numlockx off - without the "run" and without the quotation marks. ...sorry if this sounds stupid, I just want to make sure that your mistake is not there – Paul Hänsch Oct 19 '13 at 17:08
  • Is this in the upper right corner of your keyboard a "scroll lock" key? If so, it could also have to do with this behaviour. – Paul Hänsch Oct 19 '13 at 17:13
  • It sounds like your laptop has a built-in way to use certain keys like a keypad, even though it's not marked on the keyboard. My best guess is that fn+scroll lock sets it, but you should get the manual for you model at Sony support. – chaskes Nov 19 '13 at 23:56
  • The numlock can often also be set to default on or off in the bios. – Alistair Buxton Nov 28 '13 at 2:51
  • This is not a Sony's issue. It is not happens with Windows. Only in linux. In my case it is Mint Rebecca. – Kostanos Mar 12 '15 at 18:18
