HDMI stopped working after an upgrade [SOLVED]

A few weeks ago I upgraded Arch and my laptop stopped seeing a HDMI monitor. I did what was described here: https://archlinux.org/news/nvidia-590-d … l-modules/, but it didn't help. How can I debug this?

Re: HDMI stopped working after an upgrade [SOLVED]

What does `pacman -Qs 'nvidia|kernel'`show?

https://wiki.archlinux.org/title/Dynami … stallation

pacman also told you about the optional deps of the dkms package when you installed it. And there would have been errors when the module failed to build. Always read what pacman tells you.

Thanks, but... I hate to say that, but I still don't know what I should do now...

Read the first line in the link. Carefully.

Re: HDMI stopped working after an upgrade [SOLVED]

Thanks, and sorry. Somehow I was sure that I do have linux-headers installed. I installed that package and everything works fine now.
