SInce upgrading to 11.4, I no longer seem to be able to use real-time 
scheduling. If I just try something like:

chrt -r 1 ls

I get

chrt: failed to set pid 0's policy: Operation not permitted.

I have set what I believe to be correct settings in /etc/security/limits.conf, 
i.e.:

@realtime       soft    cpu             unlimited
@realtime       -       rtprio          100
@realtime       -       nice            -20
@realtime       -       memlock         unlimited


The command "groups" outputs:
users video realtime

and the command "ulimit -a" outputs:
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 40
file size               (blocks, -f) unlimited
pending signals                 (-i) 63885
max locked memory       (kbytes, -l) unlimited
max memory size         (kbytes, -m) 6961752
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 100
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 63885
virtual memory          (kbytes, -v) 8235840
file locks                      (-x) unlimited


What am I missing? What might I have lost in the upgrade from 11.3 -> 11.4?
