Ulimits -l problem with ardour5.12?[SOLVED]

[Aquarious12]

hello friends need help in ulimiit -l problem in ardour5.12.when i change the value in limits .conf file it doesn't create any difference in the output of ulimit -l i.e. 1024 in my case

i did made group realtime add my user to it and change the limits.conf file with
@realtime - rtprio 99
@realtime - memlock unlimited

i dont know what should i do exactly after doing the changes should i log out or shutdown or restart . cause the out stays the same all the time . please guide me through this.

EDIT : I did try a new thing that i added the line narch-music - memlock unlimited
@realtime - rtprio 99
@realtime - memlock unlimited
narch-music - memlock unlimited

after getting the expected result i did restart and then take look but it stayed the same. after deleting that line from the file it didnt change it solved the problem.thank you for help ; you guys rock!
