Downloading mobian now and I'll try another SD card as wellOK, now I tried it with the ubports image. Same issue... Black screen after some seconds a white flash, then again black. I don't think all this images have the same problem as ubtouch is not depending to mobian.
Okay, so I switched to mobian on a different SD card. First boot attempt, no video out. I plugged into power and tried to boot, no luck. Long pressing the power button for 10-15 seconds to force power it off, and then booting again worked.
Reflashing the working mobian SD card with manjaro resulted in the same non-booting issue.
I'm thinking this might be 2 problems here.
- The occasional non-boot on mobian, fixable with a hard reboot. This is similar to some issues I've had with the PBP, where it seems to occasionally get in a weird power state.
- It looks like there may be an issue with the Manjaro Alpha 2 image booting on Pinetab.

Yes, I had the same issue with the Manjaro Alpha 2 image. My gut feeling is that it might be related to change of LCD panel right before Early Adopters edition was shipped out. Something like different LCDs require different drivers, and old images ship with old driver, thus not working with new tablet edition.
But that's only my speculation.

Yep, that was my experience so far - Mobian was the only image that I found working.

As said, the same image not working from sdcard is booting properly when bootet from internal storage. So it is not just an issue with the image I use.

Right, you have some different issue, sorry for hijacking your thread. And I don't have any helpful ideas for you. Maybe try asking in IRC?

Manjaro doesn't work for me too. Turning on the pine tab I see the lcd backlight only but no manjaro logo or any other sign from display.
Mobian works flawlessy

Yesterday I tried 20200908.img from SD, video output was OK. Today I tried 20200910.img and also no screen, just backlight. Back to the mobian-pinetab-20200908.img and did an apt-get upgrade. Everything is OK. Strange!

I'm having the same issue. About to try postmarketos-phosh from sdcard but I know what to do next: flash mobian!

I could boot Arch from sdcard. So it is no fundamental problem...
