Arch Linux

Please try the two kernels from https://bbs.archlinux.org/viewtopic.php?pid=2059777#p2059777 and see if they both have the issue.

Ok, it might take some time because I'm in school and kind of swamped with homework. I'll do it on the weekend at the latest.

[1] is a completed bisect, you could check the last known good from [2] and first known bad [3] see if you get the same results.

[3] https://bbs.archlinux.org/viewtopic.php?pid=2059812#p2059812

Not OP, but I also have the same issue on a framework laptop.

[2]/r4 works correctly
[3]/r5 does not work (backlight flashing)

Thanks & please let me know if you need anything else!

Try the fix from [1] on any kernel with the issue. Try the kernel from [2] without that fix. [2] reverts the following ( I had to revert the first three commits in order to revert the last one )
git revert -n 0d0f5ca7f241edf07f90599e4e7fadf1ddce97db # drm/i915/display: Fix handling of enable_psr parameter
git revert -n f6bb739e61eb92bad3dcf4c336b91864d51f9503 # drm/i915/dsi: fix dual-link DSI backlight and CABC ports for display 11+
git revert -n d9d2625dafe29324fe01ecba684ce48a70ec322c # drm/i915/dsi: filter invalid backlight and CABC ports
git revert -n fc6aff984b1c63d6b9e54f5eff9cc5ac5840bc8c # drm/i915/bios: Split VBT data into per-panel vs. global parts
[3] 0d0f5ca7f241edf07f90599e4e7fadf1ddce97db looks as though it was intended to fix this issue or a related one introduced by fc6aff984b1c63d6b9e54f5eff9cc5ac5840bc8c.
Edit:
Upstream bug report [4]

[4] https://gitlab.freedesktop.org/drm/intel/-/issues/6993

The fix in [1] (i915.enable_psr=0) did not work. I tested on linux-5.19.12.arch1-1 (the current version in the repos).


[2] (linux-5.19.12-1.1) works as expected. (removed i915.enable_psr=0)


Again, please let me know if you need anything else.

Upstream would like some additional info in the upstream bug report [1].

I have the same problem with a CLEVO NV41MZ. Is there anything I can do to help? I'm going to do some debugging and try the things you mentioned.

I have the same problem, also a Framework 12th gen. I haven't tried downgrading or other fixes, but I'm happy to help if I can.

For what it's worth, connecting an external display seems to mostly work. I can't start KDE, but I can at least get into the system without chrooting.

@loqs Does https://gitlab.freedesktop.org/drm/intel/-/issues/6993 really refer to the same issue? Behavior seems to be a little bit different and the bisected commit is a different one.

I had the same problem with 5.19.12, but building upstream on commit 987a926c1d8a40e4256953b04771fbdb63bc7938 everything is working fine again.

@TrailingEdge sorry about that could you create the upstream bug report?
Edit:
The alternative would be to wait for 6.0 to become stable and the issue would presumably resolve itself.

Shouldn't this kernel be moved back to the testing repos? It seems to break all intel laptops (I've tried booting on my intel school laptop and it's also broken)

I was working on submitting a bug to upstream but it seems like it's already fixed in their most recent commit(https://cgit.freedesktop.org/drm-tip, fd2f9b9a4178e667adad268a662eb8a9c0ddc8f8).

Between TrailingEdge & I being able to use more recent commits I think the best bet is to wait for 6.0.

I am having this exact issue on a HP 840 laptop. If the computer wakes from sleep, the screen just flashes on a completely black screen.

I'm experiencing the same issue on a Dell G15 SE laptop. Rolling back to a kernel before 5.19.12 fixed the issue. (In my case, 5.19.8, since that was the prior version I had when I updated my system and received the buggy 5.19.12 kernel)

My issue is resolved when I tried 6.0.0 using linux-mainline from AUR so I'll be waiting for 6.0.0 to appear in the repo's

so what will be the approach forward now? Do we wait for 6.0.0 or will the bug be sorted in 5.19.12?

This hurts enough I'll release another 5.19 kernel before starting on 6.0.

That's great news. Hopefully within a week or something then? What a great community. I am here to stay :)

Looks like you can wait for 5.19.13:

5.19.13 in [testing], please verify it's fixed, if you're able.

Works for me on Framework with Intel 12th Gen.

Works for me on the Clevo NV41MZ too

Works for me (framework 11th gen)
