so I got a USB C DP-alt to HDMI dongle for my #PineBookPro but couldn't get a picture out of it so I plugged it into my OG #PinePhone (PinePhone Amateur I guess you can call it now?) to see if it was a software or hardware issue and can confirm the dongle works so now I am tooting this toot from my pinephone original ON MY 55" TV
in 4K UHD
@msh Yeah..as I understand it, the driver isn't in the current kernel for many arm distros on the PBP.
It used to work great on mine for a while, then stopped a couple of Manjaro updates ago
I know it's a software issue, because I can boot from an SD card with an older version of Manjaro on it and the secondary monitor connected over USB C works every time.
Boot off the current version, and the secondary monitor no longer exists.
It is unfortunate.
@paradroyd It WAS abailable for awhile but in kernel changelogs for I sawthe following for linux 5.10.38-1:
[ Vagrant Cascadian ]
* [arm64] DisableUSB type-C DisplayPort in pinebook pro device-tree.
@msh Yes..I saw something from one of the Manjaro devs saying that Pinebook Pro support for USB C video was essentially a special hack that they'd done, and now that they're using the mainline kernel, it's not there anymore.
Really hobbles it for me.
It's nice to have a laptop with essentially infinite battery life, but it's not really usable for presentations with a current kernel because of this, IMO.
@paradroyd maybe I have to find or build a dtb that includes it again, and file a bug report to have it restored and maybe then I will get an answer when my report is rejected with wontfix LOL
