Lost my second display - WEF - 06-01-2022
Hi,
Just updated (Shipped Manjaro, Firefox, etc.) and now my second display is not seen in display configuration and does not work anymore. It was working and had been for months. Set up is through the pbp docking station. Was working with HDMI (except no sound), now does not work through HDMI or serial cable. Anyone know how i can get this working again? Display configuration settings are totally greyed out as if there is only a laptop screen.
Like i said this was working literally 15 minutes ago before i did the update (that came out on 5/31/2022 i believe).
I have rebooted and plugged and unplugged and any simple things i could think of.
Thanks in advance for any ideas-

I don't currently use manjaro at the moment but I did in the past, here's what I think happened.
Manjaro uses a patched kernel for the pinebook pro in order to get DP over USB C working, this is the protocol which allows for the dock to work (even if the dock has hdmi instead of display port).
This means that the new kernel is probably missing the patch.
You can try looking in you package cache for pacman if you still have the old kernel laying around
(the cache should be at /var/cache/pacman if memory serves me right).
You should also look at which kernel you have installed exactly.
Run
Code:
pacman -Qq | grep linuxIf the installed package is just "linux" (followed by a version) then try looking for a pinebook pro specific kernel in the manjaro repository.
Hope that helps,
User

I am running the stock linux that came with the device.
Here is the output of the command:
archlinux-appstream-data
archlinux-keyring
archlinuxarm-keyring
linux
linux-api-headers
linux-firmware
linux-firmware-whence
util-linux
util-linux-libs
I expect you are right, i must be mising the patch to make it work now.

Right so that is "upstream" linux package. The "linux-pinebookpro" package is avaible in manjaro's core repo but it is an older version.
I believe the main manjaro linux kernel (the one you have) SHOULD work with your external display.
Check the pacman cache for an older version.
Otherwise, this repo: https://pacman.kiljan.org/archlinuxarm-pbp/os/aarch64/ Contains linux-manjaro-5.18.1-3 which should work with e-DP1.

Yes I also used the same repo you mentioned and it has worked for me, I hope it will also work for him too. I was also searching for it and then found it in some other forum here.

still no fix?...have to roll linux-manjaro kernel back to the 5.17 update i did on Kiljan's arch when using external hdmi.
does the manjaro team care about getting it patched ... are aware of it?
btw i use the downgrade/aur script to go back and for ,when needed,works like a charm.
