pinebook black screen when booting with "different power mode than last used"

[mr.angeli]

Hi everybody,

same issue here.

I re-flashed the OS in eMMC (Manjaro-ARM-kde-plasma-pbpro-20.02.1-emmc-installer-20.02.1.img.xz flashed with Etcher on SD)
The system works good, but sometimes doesn't boot...

I noticed that when it boots:

• orange light for a few seconds
  
• short blinking green light
  
• green light
  

when it does't boot:

• orange light for a few seconds
  
• long blinking green light
  
• stuck at this point...
  

Also at start, desktop luminosity is very low: I need to adjust it by pressing Fn + F2

Have you managed to solve the issue in the meantime?
