Bug report: nvidia-bug-report.log.gz (614.8 KB) OS: openSUSE Tumbleweed Kernel: 6.6.3-1-default Nvidia driver version: 545.29.06-18.1 GPU: 1060 3GB The problem starts at system startup, i get a really long startup, the splash screen appears glitched with artefacts, goes blank, and the screen then briefly shows alternating lines: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 1 [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 1 etc… The system on X11 Gnome works then more or less normally, except it sometimes doesn’t wake up from suspend, or takes a really long time for the image to display when waking up. Same thing happens, when suspending, takes a really long time, i get a glimpse of those lines, and the same thing at shutdown - takes really long time, blank screen, then those lines above appear, and after a while it eventually shuts down. Wayland session in Gnome is unusable. If the artefacts don’t show up during the session, waking up from suspend glitches the entire screen with artefacts, blinking and stuttering cursors, and all sorts of glitches. It’s impossible to log in at that point. Here’s the journalctl | grep nvidia output: nvidia_journalctl.txt (28.8 KB) Thanks for reading!

Same thing here. Just updated Fedora 38 from 535.129.03 to 545.29.06, and both Kernel versions v6.6.3 and v6.5.10 start showing these error when I connect external displays to me Laptop: kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: ACPI BIOS Error (bug): Could not resolve symbol [^^^PEG1.MASP], AE_NOT_FOUND (20230628/psargs-330) kernel: ACPI Error: Aborting method \_SB.PC00.LPCB.EC._Q27 due to previous error (AE_NOT_FOUND) (20230628/psparse-529) kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: ACPI BIOS Error (bug): Could not resolve symbol [^^^PEG1.MASP], AE_NOT_FOUND (20230628/psargs-330) kernel: ACPI Error: Aborting method \_SB.PC00.LPCB.EC._Q26 due to previous error (AE_NOT_FOUND) (20230628/psparse-529) kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 kernel: [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Flip event timeout on head 0 Only using the internal display of the Laptop works fine, but as soon as I attach external displays it starts failing. After I downgraded the system to use 535.129.03 again, everything works as before (tested on v6.6.3). Doesn’t even need Wayland and/or Xserver (both fail), but even just Linux TTY failes. GPU: NVIDIA® T1200 4GB Quadro (Turing)

The nvidia-drm fbdev option is experimental, so if you have issues with it set, just disable.

I don’t have that option set. I only have options nvidia-drm modeset=1 without fbdev - I think that option doesn’t even exist with the older drivers, so I never knew about it.

[ 9.655729] fbcon: nvidia-drmdrmfb (fb0) is primary device points to the option being set, likely by fedora packages. Please check using grep fbdev /etc/modprobe.d/* /lib/modprobe.d/*

[image] generix: grep fbdev /etc/modprobe.d/* Hey, thanks for responding! I did check, i do have those options in /lib/modprobe.d/50-nvidia-default.conf Should i delete the whole file, or just the fbdev part? Or leave the file, and delete the contents? What do those options do anyway? EDIT: I also have dual monitors, if that’s relevant.

Thanks, i’ll try it and report back. I kinda need the computer for a while now though, so later. :) In case something weird happens.

It’s default enabled in fedora https://pkgs.rpmfusion.org/cgit/nonfree/nvidia-kmod.git/tree/make_modeset_default.patch add nvidia-drm.fbdev=0 to the cmdline

Oh, really. nonfree/nvidia-kmod.git - nvidia-kmod Ok, that would explain why it is active and might causes these issues when I have not enabled it. I’ll have to test that later, I downgraded the driver earlier to get my setup back to work. Thanks for the pointer, I was scratching my head about that.

Ok, i tried fbdev=0, the flip event timeout message seems to be gone, and the startup process was faster, as it should be. I then tried the Wayland session, but it still wasn’t good, black bars flickering on screen in games, and some windows. I tried X11 again, works ok but the refresh rate is set to 60Hz, not 75Hz like i set it initially. Now, when i try to set the refresh rate to 75Hz, gnome session crashes, and tells me to log out and try again. I also got a third display for some reason (i only have 2), that is set to 800x600, 60Hz, says 10" Unknown display, and is positioned to the most right. I think i’m going to try to revert the driver to an earlier one… This isn’t working too good. I might have more luck with an earlier version.

Don’t delete the file, just set fbdev=0 instead of 1, then recreate the initrd sudo dracut -f and reboot.
fbdev=1 is for having a hires, accelerated text console.
