Hi all, OK, my MythTV frontend build is progressing, hooray! When I press the power button on this frontend, I want it to just shutdown, no questions asked. Currently when I press the power button, it pops up a nice dialog box asking if I want to Cancel, Restart or Power off (default is to power off in 60 seconds). Does anyone know how to remove or suppress this confirmation box in Ubuntu 20.04? Thanks!
