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.
