Type of device : Display tablet
Brand and version of the device: Huion Kamvas 13 gen 3
System : Ubuntu Studio 24.04.3
Description of the issue (you can include screenshots):
So I need this tablet to work with a single usb-c data cable to my laptop.
It used to work perfectly until some days ago, when it gave a No signal error followed by Power Saving mode, and hasn’t recovered since.
It works on WIndows, and on my desktop via the 3-in-1 cable on Ubuntu studio, but since I need the portability I have to have it work on my Linux laptop.
What I tried out so far:
Drivers reinstall
lsusb / lsmod recognizing the tablet on the system
System up to date
Laptop is powerful enough to power and send video to the tablet
Tablet can be used as a screenless tablet, proving the drivers work
Tried to congifure the MOK in the secureboot to sign the drivers. It seemed to make the tablet work for a moment but after booting, it came back to the same errors.
I searched everywhere for a solution but I can’t seem to understand where the problem lies.
It might be the USB C cable that can’t pass all the signal or something else wrong with it. Is there a way to use the 3-in-1 cable on the laptop? To test if the tablet is fine.
Just tested it out, the 3-in-1 works. Actually, more like 2-in-1, because one Usb and the HDMI is enough to make it function. One issue I saw was that when I booted up the laptop, the tablet started working fine until post-login, where it went straight to no signal. So yes, the usb-c cable has enough streaming power from what I see.
Okay so the usb-c cable is the most likely culprit then… or maybe the usb-c slot on the laptop that actually has a problem. If you know someone who has laptop/computer that has usb-c slot you can borrow, you can try the tablet with the usb-c cable there, if it failed to give signal then the usb-c cable is at fault, if not then the laptop usb-c slot might be the culprit.
I had several no signal problem with my old monitors before, most of the time it is the cable, the jack, or the slot on the computer that was the problem, most likely because wear and tear (plug in-plug out). Solution was replacing the problematic parts unfortunately.
Hmm I tried searching reports on Linux update that make USB-C connection have problems, but to be honest I have no clue how Linux OS works. But I saw few forum post that discuss what seems to be USB-C problem after an update.
