Screen-off = dead phone
#1
I have been trying different distros on my Pinephone, and I love the layout and speed of Ubuntu Touch. However, whenever I turn the screen off, it will not wake up again (the screen flickers and then goes permanently black), and I have to hold the power-button for 10 seconds and boot it back up again. I haven't had any such problem on the other distros, so it clearly seems software-related.

This problem occurred on the latest 5/6 stable version downloaded from here: https://ci.ubports.com/job/rootfs/job/ro...stemimage/

Is this a known issue? Is there a workaround? 

Thanks!

@okgo  Have you tried a 2 or 3 second press of the power button? I recall experiencing the screen flash like that some time back, and holding the power button for a few seconds worked for me. I'm currently running my PinePhone with UBPorts on the KernelUpgrade channel, and I'm not seeing that quick flash and back to black.

I tried various power-on methods... and since it flickered the screen and then went black again, it makes me think that something was attempted and then failed - rather than that I wasn't hitting the button right. But I'm all ears for solutions!

I'd suggest trying the kernel update channel. At this point it works better for me than stable. If you don't like it you can always change back.

I've had the same problem with Ubuntu Touch, but I haven't tried the "kernel update channel". I'll look for it.

Is this what you meant? https://ci.ubports.com/job/rootfs/job/ro...elupgrade/

I've confirmed that the problem with the blank screen does not occur with the kernel upgrade image.

Yes, I also confirm that downloading from here worked without the dead-screen problem https://ci.ubports.com/job/rootfs/job/ro...elupgrade/

But unfortunately UbuntuTouch just doesn't seem to be there yet. Camera doesn't work, Firefox, Yubikey, and a real Bitwarden client missing...
