keyboard toggle turns off num lock led

[SteliosSk]

I have installed Ubuntu trusty in my desktop PC. I use Latin (English US) and Greek keyboard layout.

I have changed the default key-combination (Super+space) to (Shift+Alt L) in order to toggle between the two.

My problem is this:

I have the num lock on and the corresponding LED is on. When I press the layout toggle combination (Shift+Alt L) the layout changes and the num LED turns off. I can still type numbers though by the numerical pad. When I toggle again the layout changes, but the num LED keeps still off. This weird behaviour shows even if I change the combination to the initial default (Super+space).

At this point, I must inform you that the dconf setting (org>gnome>desktop>applications>input-sources>xkb-options) is ['grp:alt_shift_toggle', 'grp_led:scroll'], meaning that the scroll lock should be turned on - off when I toggle layouts. I must also point out that the shown parameter 'grp:alt_shift_toggle' keeps the same even when I have changed the key compbination to default (Super+space).
