[SOLVED] USB-C to HDMI problem - hp 15-dw3018nq

kammao · 2022-09-29 15:25:08

Hello!

I can't seem to figure out how to make arch find the 2nd external monitor - the one connected through a USB-C port (I only have 1x HDMI port and 1x USB-C port on my hp 15-dw3018nq laptop). I checked that the USB-C is USB 3.2 Type C.

- The computer recognizes it:

I recently switched to using mesa since I have a Tiger Lake system and the xf86-video-intel driver was not working properly.
Any ideas on how to approach solving this issue?

Thank you!

I recently switched to using ~~mesa~~ Xorg modesetting since I have a Tiger Lake system and the xf86-video-intel driver was not working properly.

Shouldn't impact this.

Bus 001 Device 004: ID 343c:0000 xxxxxxxx USB Type-C Digital AV Adapter

Brand & model of that device ?

Check the user manual for your laptop, does the usb-C port support DisplayPort over USB ?

kammao · 2022-09-30 12:23:51

The brand an model of the device would be: MYRIA MY8745

I couldn't find information regarding the usb-C supporting DisplayPort unfortunately. So i guess it's because of my hardware..

I already have the only HDMI port in use with an external monitor. If I want to plug-in another monitor I suppose I'll have to buy a docking station? I also saw some HDMI adapters that you plug into the USB ports (According to laptop specs I should have 2x USB 3.1 ports).
I know this is a hardware issue but do you have any idea if the USB - HDMI adapter/ a docking station would work for an additional display? Would arch support this?

USB-C has several optional modes of which DP-over-USB and thunderbolt 3 are the 2 most common ones.
On hardware that supports them there should be logos present , see https://en.wikipedia.org/wiki/USB-C#Alt … ifications

It's rather common for manufacturers to provide those modes on only 1 or 2 of available ports ...
Check your hardware for those logos, especially around the usb-c connectors.

Incase you don't find any of them the usb-c hdmi cables won't work.

DisplayLink sells devices that can provide hdmi / dp over any usb connection, but their performance on linux varies a lot.

Whether a usb hub or a docking station can provide those coinnections depends on the hardware inside of them .
Some docking stations / usb hubs rely on a host that supports those alternate modes, others implement the functionality themselves .

There have been reports of people using dell or lenovo docking stations that worked fine on archlinux (sometimes requiring firmware updates) .

USB4 devices have mandatory support for DP over USB-c, make sure your next system supports usb4 .

Thanks a lot for the detailed explanation! It is tremendously helpful.

I will try to setup a dock and see how it goes.
If not, I already set up arch on my PC as well and there I can use the multiple video card ports available for multiple screens..
