I also experienced this weird NumLock state described by Egmont (5 is a digit, the rest are cursor keys).
I only use one keyboard layout (Hungarian) and don't want to switch it to any other, thus I deleted the English one in the System Settings / Text Entry. But after startup my keyboard layout is mostly set to English (which is also described by others, e.g. http://askubuntu.com/questions/362973/keyboard-layout-switches-to-english-each-time-i-reboot). Setxkbmap shows the following: $ setxkbmap -query rules: evdev model: pc105 layout: us So I have to manually switch to Hungarian either by 1.) clicking on the only Hungarian item in the keyboard indicator, (Setxkbmap shows: rules: evdev model: pc105 layout: hu,us variant: , ) 2.) or entering setxkbmap hu in the terminal. (Setxkbmap shows: rules: evdev model: pc105 layout: hu ) But after this and using any modifier key (e.g. switching tasks with Alt+Tab or switching desktops with Ctrl+Alt+cursors) I face the mentioned inconsistent numpad state. BTW numlockx says: $ numlockx status Numlock is on Since I have to do the layout switching only once after startup I overcame this faulty behavior with a script starting automatically after login, as follows: #!/bin/sh setxkbmap hu numlockx off numlockx on -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1247668 Title: NumLock turned off on layout switch Status in “gnome-settings-daemon” package in Ubuntu: Confirmed Bug description: Extracting from bug 1218322, confirmed there by multiple users: When switching the keyboard layout using a shortcut (such as Alt+Shift), NumLock functionality is (mostly) turned off. More precisely: it goes into an inconsistent state where pressing numpad 5 inserts the digit 5, but the other numpad keys move the cursor. Pressing the NumLock key turns it off completely (pressing numpad 5 no longer does anything), and pressing once again turns it on. This means that if someone prefers to have the NumLock functionality switched on all the time, they have to press the NumLock key twice after each layout change. I find this a huge usability problem. (I don't have a LED, so I cannot tell how that one is lit.) The bug is not present when changing the layout via the indicator applet.
