In High Sierra, in order to keep my Mac from going to sleep for three hours, I would do "sudo pmset -c displaysleep 180". That worked! That doesn't seem to work in Sonoma. At least the Lock Screen numbers don't change when I do that. That is, if I want to command this in terminal, instead of with System Settings, how do I do it in Sonoma?
Got a tip for us?

man pmsetpmset can modify the values of any of the power management settings defined below. You may specify one or more setting & value pairs on the command-line invocation of
pmset. The -a, -b, -c, -u flags determine whether the settings apply to battery ( -b ), charger (wall power) ( -c ), UPS ( -u ) or all ( -a ).
Use a minutes argument of 0 to set the idle time to never for sleep disksleep and displaysleep
pmset must be run as root in order to modify any settings.

OK, apologies. It's all working now. One mistake I was making was using that command WHILE the System Settings Lock Screen page was open. That won't work. I neglected to say that I upgraded from a MacBookPro2011 to a MacBookAir M2 with Sonoma. Thank you, everyone.
