USB-C on Lenovo X1 laptop stopped working for display

Hi everyone,

Since googling the error I am facing yielded no result, I’m posting this here.
This morning I encountered a new problem with my laptop: when connecting a USB-C monitor, the said monitor blinks once, then displays the classic “no signal from your device”. The same happens with 2 other USB-C monitors, and also with the two USB-C ports of the laptop. This started happening without a reboot, but after closing the lid and reopening it a few hours later. I also tried rebooting a few times, without change.
Also, it works with HDMI on another monitor (can’t test on mine), so I think the issue really is related with the USB-C ports.

I’ll start with the dmesg -w logs when unplugging and plugging the USB-C connector of the monitor:

This last line is what I couldn’t find online, and I don’t have enough knowledge to understand where to start looking …

Now some system information in case it’s useful. It’s an X1 gen 9 Lenovo laptop with an up-to-date Gnome-Manjaro. The same problem happens both on Xorg and Wayland.

Thanks so much in advance to anyone who could provide some insights on this, and I hope I’m not missing anything obvious.

Adding some more information, a USB-C external SSD plugged into the same USB-C ports works, but some errors appear as well when plugging it in:

Simply means: response takes too long and cancel. Why this happens? No idea. Needs research.

Probably try a different kernel version.

Or it is in power saving mode in battery mode. Thus, is suspended, powered off. Maybe not enough power?

Thanks for your answer @megavolt.
This is very useful:

$ sudo pacman -S moreutils
$ errno 110
ETIMEDOUT 110 Connection timed out

Thanks for showing it.

Regarding the laptop, I am very confused, it started working again.
I rebooted with the 5.15.145-1 kernel: there, it worked.
Next, with a subsequent reboot I switched back to 6.1.69-1, and …it kept working!

Maybe the power thing? A real mystery. I’ll try to investigate a bit more before closing the thread.
