I too have had the persistent number lock problem on installing on  lap tops.  I am not sure whether there is something retained in short term memory which  resists the tweaks route.  What I tend to do on fresh installations is follow out the Language and keyboard settings after installation, double check tweaks num lock setting,  and then type something in Libre Office to check that all is working OK typewise. Then log off and switch laptop off , leave switched off for say 10 or so minutes  and then reboot.  That seems to do the trick on most occasions.    It is a bit of a hassle; not sure why this all has to be done, i.e. not done at the initial installation stage.    I found this very off putting when embarking on LL, but persisted with the help of the forum. 
Worth the effort in the long run as IMHO  the benefits of LL outweigh the initial hurdles of setting up.
