<![CDATA[Black screen]]>Hi
I am trying out Rhino Linux with Lomiri on a PP.
I have installed it on a sd card.
The problem is that when I boot the OS i get a black screen, nothing more happens, it just stays that way. I let the phone be like that for several minutes.
Towboot is installed on the phone and I have Ubuntu Touch on emmc and Mobian on another sd card. Both works.
I tried to reinstall Rhino with a new download, same black screen when booting.
Is there anyone else with similar problem?
Or having a solution?

  1. The WiFi issue is due to the Mobian kernels, which do not have the firmware built in directly, unlike my older okpine kernels, but mine seem to struggle with Lomiri on 2025.4, which is why we switched to the Mobian ones
  2. The Lomiri black screen for 2025.4 on the PinePhone is definitely a hardware acceleration issue, the PinePhone Pro does boot it correctly

I will see what I can do about fixing both of these problems. I have not bumped my kernel in a long time, so hopefully updating it would resolve the issues, but I am so far out of the habit that it will take a bit to fix. I will also take a look if the WiFi issues can be fixed externally without new kernels, and what dependencies might still be needed to get Lomiri working on the OG PinePhone.
Once again, thank you massively!

2025.04 Unicorn boots but has no working Wifi
2025.03 Unicorn boots and has wifi
Both: Doesn't scale the windows for open apps, they all opens in landscape. Open windows doesn't detect the size of the screen, all of them scales outside the screen boundries.

I am guessing the Unicorn Mobile images should still work, will do some testing

I will try to look into it over the next few days, though it might not be until the weekend (hopefully sooner!). Thank you for reporting the issue, as we have not had a lot of users of the PinePhone images besides ourselves in testing.

A few more quick questions:

  1. Do the 4 tuxes pop up at the start, before it goes black, or is it black always?
  2. Did you happen to also try a Unicorn Mobile image? If that one boots correctly, then you should still be able to install Lomiri on it after.

We did have to re-split the kernels recently for these new images on the PinePhones, so my guess is that is likely where the issue is happening; that should become obvious if the Unicorn Mobile images don't work either. Unfortunately, my testing on the OG PinePhone was limited this development cycle and I was mostly focused on the PineTab2 and PinePhone Pro, so that is my fault for not thoroughly testing it more.

In any case, this will surely help us with releasing updated images, so once again thank you for the report!

Have now waited over 30 minutes and nothing happens. The screen stays black with background light on.

Sorry but I'm out of town until tomorrow. I report back when I have tried again.

Thanks😎
I'm happy to be here.
You did an amazing work on Ubuntu Touch for the Pine64 devices so I just needed to join this party too.

First boot on the Lomiri images, for whatever reason, takes several minutes to fully load. The PinePhone may be extra slowed due to lacking GPU acceleration. I would try leaving it for upwards of 10 minutes, and if it still does not work, then get back to me on this thread.

Cheers!
