After update, problem with HDMI video

English Hardware
1

Hello everyone,

I have a laptop Inspiron 14R 5437, and I made the last update of Tumbleweed. Since this update, my HDMI output is detected just as audio device, and I don’t have any signal of video to the external monitor.

I tried to figure this fix out but was unsuccessful.

Follow some information about my system:

cat /etc/SUSE-brand

Also, I put my dmesg output in pastebin: dmesg - Pastebin.com

Please, if you have any clue or information that can help, I will appreciate.

Just a few wild guesses, since your problem might be related to the current Nvidia driver needing a patch to build on kernel 4.10.x:

  1. Is this the first update in which you see kernel 4.10. or did it work before? Were you using the proprietary Nvidia driver or the nouveau driver?
  2. Do you still have a kernel 4.9.x installed, and does HDMI work with it?
  3. Is the HDMI output wired to the Nvidia GPU? Or did you use the system just with integrated graphics?
  4. From dmesg the Nvidia GPU is likely normally OFF: what do you use to switch it on? Bumblebee? DRI_PRIME?

Hi OrsoBruno,
Follow the answers:

1- A) Is not the first update, in fact, I’m using the Tumbleweed since October 2016 and I always try to keep my system updated. I’m using the nouveau.
2- A) I don’t have anymore the kernel 4.9.x anymore, but worked as well before the last update.
3- A) It’s the Intel integrated graphics that is responsible for my HDMI output
4- A) To be honest, I didn’t change anything after the installation, I suppose that this behavior is the same since the installation. I never switch it to on.

Is there any Error in /var/log/Xorg.0.log?

Hi Sauerland,

I found just these lines in Xorg.0.log:

33.114] (II) config/udev: Adding input device HDA Intel HDMI HDMI/DP,pcm=3 (/dev/input/event11)
33.114] (II) No input driver specified, ignoring this device.

No other reference to HDMI on this file.
