Current behaviour (Fedora 39)

Behaviour with 2 of my monitors: plug in, laptop screen goes blank, monitor does not appear to acknowledge a signal. Remove cable, re-plug cable: monitor wakes up and works.

Behaviour with another (older) monitor (tv): no amount of re-plugging makes it work, but my laptop screen goes blank and according to inxi the external screen is detected.

Past behaviour

I don’t recall these problems with Fedora 38. (also I did not have these problems with Ubuntu 22.04).

Specs

I have an 11th Gen Intel processor, Iris Xe graphics, running Fedora 39 with Wayland and

inxi Graphics:
  Device-1: Intel TigerLake-LP GT2 [Iris Xe Graphics] vendor: Framework
    driver: i915 v: kernel arch: Gen-12.1 ports: active: eDP-1
    empty: DP-1, DP-2, DP-3, DP-4 bus-ID: 00:02.0 chip-ID: 8086:9a49

debugging info

This is the journalctl output after plugging in the screen that doesn’t respond:

I plugged in the monitor and blindly ran inxi, here’s the Graphics section:

Any tips gratefully received! Thanks.

Two thoughts:
try a different HDMI cable
see if an older kernel works better

With graphics its the kernel that is important not so much the linux user space.

Thanks for reply. Tried several cables. Same. Will see if I can get older kernel with fedora 39

I would highly recommend closing this and making a post in the official Framework forums, as the staff has dedicated Linux support people that will be able to help with you there. Reply to me here when you make it and I can take a look as well. At the end of 2023 I migrated from the 11th gen i7 board to the Ryzen 7 7840U board in my Framework, but I’ll be able to test the original 11th gen board when I get back in town next week.

ok I can’t find a ‘close’ button, but if you can, that’s fine.

I’ve already asked there, too:

But don’t worry, I can just plug it twice and live with it; it seems to work mostly. I was posting in case someone said “oh yeah, I had that, you need to put this kernel parameter” or something similar. You know how these little things eventually bubble up into an annoyance worthy of spilling some ink on a forum! But it’s not so important.

Thanks for your help!

You already found it when you marked the solution – :sunglasses:
