No external monitorvia USB-C over Dockingstation

[marty-mcfly]

I downloaded and extracted the 6.5 pbp.tar.gz as was directed.

https://xff.cz/kernels/6.5/pbp.tar.gz

When I extracted it, the /lib/modules/ directory did not contain something with 'dirty' on the end but was this:
/lib/modules/6.5.7-00508-gb1f5e9cc01a2

Should I try to use this or will the lack of 'dirty' mean that this is not the correct file and won't work?

Thank you much!

I used the Manjaro-ARM-xfce-pbpro-20.04-emmc-installer-20.04.img to install Manjaro on the eMMC, then updated it to the latest version.  Without doing anything else, a second monitor shows up automagically with HDMI via USB-C, but the sound doesn't work.  

Does sound work with megi's kernel?

Meanwhile, I tried the last two versions of Armbian, and HDMI via USB-C doesn't work at all.

How did you get this older version 20.04 of Manjaro? Do you have a link handy?

How did you get this older version 20.04 of Manjaro? Do you have a link handy?

There are two versions, one to run off SD, and an eMMC installer.
https://osdn.net/projects/manjaro-arm/st...fce/20.04/
There are also both versions with a KDE desktop https://osdn.net/projects/manjaro-arm/st...sma/20.04/
Unfortunately, osdn.net seems to have server issues.  So if the page doesn't load, I would try again later.

Also, when updating, if you get an error "nss: /usr/lib/p11-kit-trust.so exists in filesystem", this worked for me:

Code:

sudo pacman -Syu --overwrite /usr/lib\*/p11-kit-trust.so

Has anyone been able to get sound to work through HDMI?

I just tried Manjaro-ARM-gnome-pbpro-23.02.img from https://manjaro.org/download/ and HDMI via USB-C did not work.

I do not know the difference (besides the desktop and additional software) between that, and the updated Manjaro from OSDN.  However, I suspect that whoever wrote it did something the Armbian and Manjaro people are not doing, even with their PBP-specific distributions.

(Although the Gnome desktop seemed well-appointed, the Manjaro-ARM-gnome-pbpro-23.02.img also seemed unusually slow compared to the other distributions I've tried.)

Is alt-dp mode over USB-C working for anyone else using megi's 6.9 kernel?

For a long time I stayed on a 5.7 kernel I got somewhere, and the alt-dp just worked. Yesterday, I "upgraded" to Manjaro's linux 6.7.9-1 and found that it no longer works. Manjaro linux-lts (6.1.81-1) also doesn't support it.

https://xff.cz/kernels/ only has 6.9 now, and I see it mentioned in the changelog,

2024-05-10:
- rebased and ported everything to v6.9
- fix alt-dp mode on Pinephone Pro and Pinenook Pro, it was not being entered
due to https://lore.kernel.org/lkml/20231204020...inaro.org/
change

But it doesn't actually work. dmesg:

Code:

[  391.035095] typec_displayport port0-partner.0: Our Alt-DP VDO 0x000c46 and peer port VDO 0x101007 are not compatible (no shared pinconf 000c<->1010 (UUDD))

EDIT: Uni Accessories USB-C to DisplayPort Cable is working. Bizlink is not. On the old kernel they both did. Also running into two unrelated features that work on 6.7.9-1-MANJARO-ARM but not on megi 6.9.0-00566-g6be698fa4d94 because they weren't compiled in. Time to email.

Edit 2: All fixed in the 6.12 build.

Maybe it will be patched in a future mainline kernel.

[Dendrocalamus64]

It used to be in mainline, then they took it out for being 'too hard to maintain.' The PBP is old enough now that it's past its peak of software support and developer interest.

Still using external monitor daily via the megi 6.12 kernel myself.
