When external monitors are plugged in, the desktop slows to to a crawl (A UI update every second or so), but never display. Journal is filled with messages like:
Feb 07 18:00:34 nburgin-x1e2 kwin_wayland[2070]: Pageflip timed out! This is a bug in the nvidia-drm kernel driver
Feb 07 18:00:34 nburgin-x1e2 kwin_wayland[2070]: Please report this at https://forums.developer.nvidia.com/c/gpu-graphics/linux

Sometimes (at least once, anyway), the performance picks up again with the external monitors still plugged in. Unplugging the monitors always resolves the performance issue.
The monitors are a pair of Dell U2715Hs. They are in a Displayport daisy chain setup, plugged into one of the laptops USB-C ports (doesn’t matter which one, behaviour is the same).
This setup was working a few days ago (and continues to work fine on my work laptop - which is intel integrated only). I suspect either a kernel update or a driver update borked it (I didn’t update anything explicitly, but did install wine). I might attempt running a previous version of both the kernel and nvidia driver later, but I’ve already spent enough time on this issue instead of getting anything productive done for now.
I have since tried the following:
- Full system update
- Completely re-installing nvidia drivers (via rpmfusion)
- Clearing out the kwin configuration
- Following the nvidia guides on RPMFusion and ArchWiki
- Disabling GSP firmware through modprobe.d (
options nvidia NVreg_EnableGpuFirmware=0) - Forcing early loading of the drivers through dracut (
force_drivers+=" nvidia nvidia_modeset nvidia_uvm nvidia_drm ")
From what I can tell, this laptop has the external monitor ports wired to the nvidia GPU directly (no mux).
I currently have the BIOS set to dedicated GPU only, if I attempt to enable hybrid (which I would prefer for improved battery life), I get blank internal screen after logging in. This has always been the case with Fedora + KDE + Wayland. I will raise this as a separate issue, as I assume this is unrelated to this specific issue, but the BIOS setting I feel is worth noting for completeness here.
I think all other useful context is in the attached logs. I can add additional detail or attach other logs if helpful. nvidia bug report was taken with the monitors plugged in (otherwise they are not listed in the log).
