'restart' the LCD after a power down of the processor (u8g2)

Other Hardware Displays

Solution found:
Keep the pinModes as INPUT while asleep, but simply restart the display again using

u8g2.begin();

after waking up.

(2/10/22) Edit for anyone stumbling across this:
you can use

u8g2.setPowerSave(true);

in order to prevent the little ugly bars from showing up when the display is powered off.
