Fix: Number Pad Will Not Work in Ubuntu
Sometimes when I’ve been messing around on Ubuntu my number pad will quit working. The number lock is on, I can see the indicator right there. Toggling the num lock on and off doesn’t fix things. I found that holding 8, 2, 4, or 6 moves the cursor on the screen though.
This is an Accessibility option that gets turned on to control the cursor with the number pad. For some reason unknown to me Ubuntu chooses to turn on what it calls “Mouse Keys”.
In Gnome
- Go to System -> Preferences -> Assistive Technologies.
- When the Assistive Technologies Preferences screen opens, click the Keyboard Accessibility button.
- When the Keyboard Preferences screen opens, select the Mouse Keys tab.
- Uncheck the box labeled “Pointer can be controlled using the keypad”.
- Close out of all dialogs.
That’s all there is to it. Your keypad is now functional again.
In KDE
KDE icon > Control Centre > Peripherals > Mouse > Mouse Navigation
Untick the box that says “Move pointer with keyboard (using number pad)
Keyboard shortcut to turn this on/off
Shift-Number Lock is a shortcut for turning this ‘feature’ off and on. For some reason mouse keys do not honor the setting that determines if accessibility features can be turned on and off with keyboard shortcuts.
