[RESPONDED] HDMI monitor problems (not or intermittently available)

Framework Laptop 13 Linux
,
1

Current behaviour (Fedora 39)

Behaviour with 2 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.

Past behaviour

I don’t recall these problems with Fedora 38. I did not have these problems with Ubuntu 22.04 (and possibly 22.10 and 23.04, sorry can’t recall).

Specs

I have an 8th batch Framework laptop with an 11th Gen Intel processor, Iris Xe graphics, BIOS 3.16 running Fedora 39 and

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.

Looks like you are on older BIOS (understandably waiting for the EFI release, I imagine), but this does limit me as I am on 3.19 myself.

Let’s start off with this approach in the meantime:

  • Forget the TV for now, let’s focus on what should be the known to be working monitor when plugged and unplugged.
  • Boot to a live USB of Ubuntu 22.04.3. Test that display with this configuration.

Does it present the same behavior? If it does still happen, the next step is to test with a different set of cables and test with the expansion cards in different slots while on the live USB.

Let me know the results, from there we can determine if this is a kernel bug, bad cable or something else.

Hi @Matt_Hartley thanks for your response, and happy new year!

I booted Ubuntu 22.04.3 ok and the monitor behaved itself. I only tried it once. However, the test session was X11 (I’m on wayland) - I don’t know if that’s relevant. And I guess the monitor might not have been in the same state (I don’t know how many power states it manages, but it had recently been ON before this test). I’ll try Ubuntu again with the other monitor shortly.

Typical behaviour with 2 monitors and 2 leads is that I plugin in the morning and my laptop screen goes blank but the monitor never turns on (from power save mode). I unplug and immediately (I wait for the laptop screen to turn on again) re-plug the monitor and it typically wakes up then. Sometimes it can take a third attempt, and very rarely, a fourth. Rarely does it work on the first attempt as it should.

BIOS 3.19 - yes it seems it is not available for linux users yet.

How is the monitor in Ubuntu 23.10?

This would also be an option, as it would have a newer config for your 11th gen. But honestly, this feels like something we want to test against a current version of the BIOS as there have been significant improvements made in the current power department.

Not sure if this is a helpful response, but with the 7840U board and F39 on the 6.6.9 kernel, the HDMI card is working fine when booting up with it plugged in and when hotplugging.

Fedora 39 trumps Ubuntu 23.10 I think; Fedora being released 1 month later.

@Alex_S I don’t know if 7840U refers to a CPU but my CPU is i5-1135G7 and my kernel is 6.6.8. I’ll upgrade to 6.6.9 just in case.

New information just in: so I’ve found that after plugging monitor in, if I do Ctrl-Alt-F3 (to get a TTY which displays on laptop screen only), then Ctrl-Alt-F2, my external screen awakens.
