I am trying to get into X on my PI4 as quick as possible (trying to load a GUI app as soon as LXDE starts).
Right now I am at 17 seconds and LXDE is available. I think there is a delay between NTPD (disabled) and getting to DietPi-boot. There is about 5-7 seconds of doing (?) something.
Anything else I can do to cut this boot time down?
