I strongly hope I'm not beating up a dead horse here...
I noticed that in vanilla Lubuntu (no idea about "genuine" Ubuntu) there was no response at all on any SAK (e. g. Alt-PrtSc-K) -- dead as a doornail. So this will be a huge problem for you if something really goes all wonky and you want to force the system into logout (well, this occasionally happens here).
It turned out the keys were actually disabled in Lubuntu, and so was the whole keyboard control of the "Magic Keys"!!
Old value was 176, JFTR.
Next step requires a true root shell. Not likely to work by 'sudoing' things.
Code:# echo 180 > /proc/sys/kernel/sysrq
When I counted the LSB as Bit 0, it occurred to me that Bit 2 was not set. (The latter, however, is mandatory for the SAK to work.)
Original bitmask was $B0, but it must be $B0 OR $4, which is $B4 (180).
(Wonder whoever got the creative idea of disabling this?? And WHY? I'll be damned if it wasn't another one of those security paranoiacs...)
Lastly, if you want to get this change permanent: the value is stored in /etc/sysctl.d/10-magic-sysrq.conf
