I go to System Settings -> Input Devices -> Keyboard
Then select Advanced -> Configure keyboard options -> Caps Lock behavior -> Make Caps Lock an additional Esc
This works for setting my Caps Lock key as additional Escape. However, after reboot, Caps Lock has normal behavior again. If I go to the above setting, it is still set. I toggle off, apply, toggle on, apply, and I have the correct Caps Lock behavior again.
This works for me (the info is at the end of the forum thread above)
So, for SDDM the solution would be to place “Numlock=on” string inside /etc/sddm.conf.
I’m not sure what you mean by enabling num lock for my Caps Lock issue. Regardless, it seems like after the most recent update that Caps Lock stayed enabled after a reboot so it might have been a bug that was fixed. I will see how it goes on subsequent reboots.
