On my Samsung NP305E5A-A05US laptop, the numpad, except for the 5 key, has started acting like the arrow keys(6 moves the cursor right, 8 moves the cursor up, etc). However, holding the Fn key makes it work normally. NumLock only toggles the 5 key.
You must have your numpad not locked. If you have the numlock button, just press it, if not you can use
to install it :
sudo apt-get install numlockx
- Click on the System Menu
- Go to Preferences sub menu
- Select Keyboard
- Click on the Mouse Keys tab
- Uncheck "Pointer can be controlled using the keypad"
