[BUG] Black screen after splash screen

[mlukasek]

Bug report

Describe the bug

After updat to ESPHome 2024.12.0 I used ref: 2024.2.1 and it helped, but after the next update of ESPHome to 2024.12.2, I have black screen. Reset shows splash screen with color Ehmtx and heart and then screen goes black. The device is alive, as I can see sensor values in HA, can do OTA update, but screen shows nothing.

I noticed, that Auto adjust brightness cannot be turned off, but I do not know if it behaved this way before.

Thank you andrewjswan this works, I can see calendar, I can see my own screens, but why the 2 previous default screens are missing?

[andrewjswan]

There are no default screens in this firmware, you determine which screens will be visible, you can do this in ESPHome or in HA.

[mlukasek]

Thanks, that explains the black screen without adding any additional.
