Page flip timeout when connecting TV via HDMI

[0x70369]

NVIDIA Open GPU Kernel Modules Version

610.43.03

Please confirm this issue does not happen with the proprietary driver (of the same version). This issue tracker is only for bugs specific to the open kernel driver.

• I confirm that this does not happen with the proprietary driver package.

Operating System and Version

Description: Arch Linux

Kernel Release

Linux Alienware 7.1.3-zen1-1-zen #1 ZEN SMP PREEMPT_DYNAMIC Tue, 07 Jul 2026 05:04:24 +0000 x86_64 GNU/Linux

Please confirm you are running a stable release kernel (e.g. not a -rc). We do not accept bug reports for unreleased kernels.

• I am running on a stable kernel release.

Hardware: GPU

GPU 0: NVIDIA GeForce RTX 4070 Laptop GPU (UUID: GPU-fe73de91-af7e-a140-980d-2da2c9ab3861)

Describe the bug

I often use my laptop's HDMI output plugged to a TV, which I set to be the only active video output. Changing the frame rate/resolution/HDR settings causes the video output to simply disappear (TV shows "No Signal" message).
Since my laptop's screen is disabled (because I don't use it while gaming on the TV), the only solution is to switch to another TTY (Ctrl + Shift + Fn) and restart the system.

On reboot, as soon as the HDMI cable is connected, the problem reoccurs instantly (if I boot the computer with the cable plugged in, the video goes away after logging in into Plasma Login Manager).
Without the TV being connected, the laptop works just fine.
Manually overriding the EDID via debugfs with the one I extracted from the TV does nothing.
Reinstalling Arch gives a sliver of hope, as the HDMI output would - most of the time - return to work, but the animations (opening programs, minimizing, etc.) would be very glitchy, with lots of stutters and/or in slow motion. As soon as I touch the video settings, chaos returns.

This started happening after I upgraded the nvidia-open-dkms package to version 610.43.02, and version 610.43.03 still has this issue.
I tried rolling back to the nvidia-580xx-dkms package (currently version 580.173.02) - which is the latest before version 610 available in either the official Arch repositories or the AUR - and surprisingly the issue persisted. It's worth noting that this driver from the AUR is the closed source proprietary branch, like explained in this piece of news.

I'm pretty confident that the problem is in the Linux driver, since my w11 instance on the same laptop works as it should (even right now as I write this report).

I tested this with 3 kernels, and with all of them the issue is rampant. Output of uname -a:

• linux-zen: Linux Alienware 7.1.3-zen1-1-zen #1 ZEN SMP PREEMPT_DYNAMIC Tue, 07 Jul 2026 05:04:24 +0000 x86_64 GNU/Linux;
• linux: Linux Alienware 7.1.3-arch1-1 #1 SMP PREEMPT_DYNAMIC Tue, 07 Jul 2026 05:05:48 +0000 x86_64 GNU/Linux;

In the "More Info" section I provided some logs I collected. But here I'll highlight 2 error messages:

1. When logging in and the video stops working, this message starts cluttering the logs:

jul 09 14:37:52 Alienware kwin_wayland[1718]: Pageflip timed out! This is a bug in the nvidia-drm kernel driver
jul 09 14:37:52 Alienware kwin_wayland[1718]: Please report this at https://forums.developer.nvidia.com/c/gpu-graphics/linux
jul 09 14:37:52 Alienware kwin_wayland[1718]: With the output of 'sudo dmesg' and 'journalctl --user-unit plasma-kwin_wayland --boot 0'

2. When connecting/disconnecting the cable after the video was gone, this other message started showing up:

1379:[  394.446826] [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0
1380:[  398.448523] [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to apply atomic modeset.  Error code: -22

To Reproduce

• Install Arch Linux with the KDE Plasma desktop environment (my exact setup - with modprobe.d and udev rule files - can be found here);
• Connect the TV to the laptop via HDMI;
• Set it as the only active video output;
• Change frame rate/resolution/HDR settings;
