My PinePhone running postmarketOS is now hooked up to a hub and my TV with a mouse for input. Impressed this modest device can run multiple screens and apps. @postmarketOS (mastodon.social)

@distrowatch@mastodon.social @pine64@lemmy.ml @postmarketOS@social.treehouse.systems did you connected to the tv using the USB-C docking bar from the convergence package or a classic USB-C->HDMI ?

(asking because HDMI from docking bar does not work in my case... having the pinephone beta edition may be related)

I've used it with my PP + "convergence" hub, it worked, but I don't remember for sure if it was Phosh or Plasma.. It was Arch-based though, IIRC simply Arch? Otherwise Manjaro.

@vas@lemmy.ml thanks, i may have found my issue (related to HW, I have beta edition):
https://pine64.org/documentation/PinePhone/Revisions/PinePhone/_v1.2b/#known-issues
HDMI hotplug detection is not reliable due to a HW bug in level shifting circuitry for the hot plug detect (HPD) signal between HDMI bridge and A64 SoC, see megi’s blog post.

@Albirew @postmarketOS @pine64 Using the USB-C dock. It has not worked with any other OS on the PinePhone. This is the first time it has worked since I got the phone a few years ago. Was pleasantly surprised it functioned flawlessly.

Thanks for the feedback. 👍
Then, my issue may be either:

  1. the Gnome-mobile edition of PMOS (if different from what you installed)
  2. the beta edition of my Pinephone
  3. my lack of skill and luck

  1. I am using the Phosh edition of postmarketOS. It was as easy as plugging in the HDMI cable and the desktop appeared on my screen.

  2. Perhaps. I am using the original PinePhone.

  3. Probably luck. With Phosh on pmos there aren't any technical steps.
