Hi NVIDIA Team,

I’m experiencing a severe issue when using dedicated GPU (dGPU) mode on my laptop with KDE Plasma on Wayland.

Problem description:
When I enable the discrete GPU mode (i.e., forcing the system to use the NVIDIA RTX 4060 for all rendering), my desktop environment completely freezes shortly after logging in. The system becomes unresponsive, I cannot switch to TTY, but background audio keeps playing, indicating the kernel is still running in the background. However, the graphical session is totally locked up. The only workaround is to force shutdown by holding the power button.

This behavior happens randomly but consistently every time I try to use the dGPU mode under Wayland. Unfortunately, logs do not provide any obvious cause, making it hard to trace the root of the issue.

If I switch back to hybrid graphics mode (iGPU + dGPU offloading), the system works perfectly stable, even under high load, for long periods.

That said, I really want to use the dGPU directly for full performance in some workloads and games, and this issue is blocking me from doing that.

System Info:
Laptop model: Lenovo Legion Y9000P 2024 (Model: 82WK, international name: Legion Pro 5i Gen 8)
CPU: Intel Core i9-13900HX
GPU: NVIDIA GeForce RTX 4060 Laptop GPU
OS: Arch Linux x86_64
Kernel: 6.14.4-arch1-2
DE: KDE Plasma 6.3.4 (Wayland)
Driver version: 570.144
Display: 2560x1440@180Hz external + 2560x1600@240Hz internal (both high refresh rate displays)

I’ve attached my nvidia-bug-report.log.gz file as requested. I really hope a future driver update can resolve this, or if there are any workarounds or debug steps I could try in the meantime, I’d really appreciate it.

Thank you in advance.

How are you testing this?

I tried to test using a Live USB of Manjaro, since they have an option to boot with the proprietary NVIDIA drivers, and it seemed to me that GNOME was still slightly worse than it should (when compared to using Windows or the same live session only with the dGPU enabled) but the KDE Plasma version was nearly the same as GNOME (albeit probably slightly worse).

I tested this with Manjaro 25.0 that comes with GNOME 48 and KDE Plasma 6.3. I would also prefer to test with Fedora (or other distro) but this was the easiest option in order to test without making a full installation.

64

Also came here to say I am getting terrible performance running wayland on an intel/nvidia dual gpu laptop. I have pretty much confirmed that this is an issue specifically with the dual GPU setup. My laptop requires the intel gpu to run the internal monitor and nvidia gpu to run external monitors. Whenever I do not run an external monitor the intel gpu can handle wayalnd just fine, and if I configure wayland to just not use the intel gpu (resulting in a degraded experience with the internal display not able to function) the nvidia gpu can also hum along with very low resource usage. However any way I try to run both monitors, with either intel or nvidia as the ‘primary’ renderer and doing offloading one way or the other results in incredibly high resource usage for both GPUs and framerate stuttering on the external monitor. So this appears to specifically be an issue in the way the GPUs are offloading to each other. And I know this is only an issue with this specific combination because I also have a framework 16 laptop with the dedicated GPU option, so an AMD iGPU and AMD dGPU and that laptop runs all of the wayland environments perfectly fine with extremely low resource usage while engaging both GPUs for external monitor/offloading.

Drivers

pacman -Q | grep nvidia
nvidia-open 570.153.02-2
nvidia-utils 570.153.02-1
opencl-nvidia 570.153.02-1

I also will occasionally swap to the proprietary drivers package and things don’t seem to be that different between the two.

I also recently tried the nvidia beta drivers in the AUR that were around version 575 and did not see any change in performance with them either.

Really hoping this issue gets fixed so I am not stuck on using Xorg environments for this laptop.

Good afternoon everyone, I have an Acer Nitro ANV15-51-7837 + RTX 3050 that I bought less than a month ago, it has an i7 that works with a dgpu in a hybrid way, and I do not have a mux switch and I have no option to turn off my igpu, I am using plasma and wayland in their latest versions and I confirm that I have the same problem, I have even created a topic about it here on the nvidia forums, [Acer Nitro ANV15-51-7837 + RTX 3050] Bad performance when trying external hdmi video

66

Update, i put KWIN_DRM_DEVICES=“/dev/dri/by-path/pci-0000:01:00.0-card:/dev/dri/by-path/pci-0000:00:02.0-card” on my /etc/environment, this improve so much my performance on external monitors, but i only use if i using on charge why the battery runs out very quickly

67

The reason this kills your battery life so fast, is because you are telling KDE Plasma to run on your dedicated, higher power Nvidia GPU. It fixes the performance issue because the Nvidia GPU is rendering the desktop environment, it doesn’t have to copy from the integrated GPU.

This is a workaround and not at all a fix for the issue this thread is about, let’s not derail the conversation.

Nvidia seems to be ignoring the issue of GPU copies being abysmally slow. This issue is about the Nvidia GPU’s video output being slow when it is outputting something rendered by the integrated GPU. Please break the radio silence @amrits

I would like to use all of my video outputs on my laptop. None of the latest updates have improved the situation.

Hi, still no news I guess?

69

Thx for the heads up, the NVK driver is pretty good actually. No more laggy mouse/screen on an external display with Hyprland, had 0 expectation when installing it.
We reached the point where nouveau is actually more usable than proprietary NVIDIA drivers lmao.

An update on this would be appreciated.

Hi All,

We had several issues in the past using wayland on external monitors like half the FPS of screen refresh rate which is fixed.

I would suggest everyone to try on 580 driver and let us know about the issues in descriptive way.

I will file bugs accordingly for better tracking purpose.

72

Can’t provide evidences now, but that is absolutely not fix in KDE Plasma with 580, either on the open module or the closed source. I’ll prepare a short recording later depicting it.

73

Is this issue of sufficient detail to file a bug about? I think it is the same category of problem. I have been running 580.76.05 and if anything things have gotten worse for my setup, but I need to be running at least something in the 570 drivers to even have a chance at running games at all.

74

I’m getting consistent half refresh rate FPS on my DP connected screen on driver 580.82.07 in KDE wayland, apt package nvidia-driver-580-open. This is a lenovo thinkpad p1 gen4 RTX 3080 Laptop GPU. External monitor is a ThinkVision P24H-2L @75Hz75Hz

Kernel 6.14.0-29-generic #29-Ubuntu

> cat /etc/modprobe.d/nvidia.conf 
options nvidia NVreg_PreserveVideoMemoryAllocations=1
options nvidia EnableResizableBar=1
options nvidia NVreg_EnableGpuFirmware=0
options nvidia NVreg_RegistryDwords=RmEnableAggressiveVblank=1

This problem occurs when instructing KDE to do all compositing on the igpu, if I instruct kDE to do compositing entirely on the dgpu then performance is good, but thermals are constantly high due to the graphics card constant high power draw.
Do let me know if there’s more information I should provide.

Edit: adding information about kde:
KDE: 6.3.4

KDE Framework: 6.12.0

Qt: 6.8.3

75

I think it’s better but it still drops frames when switching workspaces on Gnome + cursor freezing

77

None fixed over here, with Optimus enabled both monitors are at 60hz but my second monitor is black, only the mouse shows, no application or desktop environment elements shows up.

Disabling Optimus in UEFI I can see the second monitor, but both my monitors go to ~30hz, awful experience.

Please state any tests I could run or information I could provide to help solve this.

Tried to catch it with Test Ufo but can’t get more than 30fps, probably because the monitor themselves are not reaching that: Imgur: The magic of the Internet

Hi @randamunanamae @krugergui

Thank you for sharing detailed information, we will look into this and update further on it.

Hi @randamunanamae,

Filed an internal bug - 5547384 to track this issue.

Can you please run this test again and capture a NVIDIA bug report during the test? Please attach it here.

What applications are you using for testing? Can you share your steps to reproduce the issue.

Thanks

Thanks for your work on the linux drivers. Using nvidia + wayland is not an issue (IME) unless you specifically use a hybrid laptop with multi-monitors.

Running `nvidia-prime glxgears` gives 120fps (2560x1600) on my built-in screen but dragging the same screen over to the external display (rated 2560x1440@75HZ) barely achieves 40-60fps.

The only way for me to be able to use both monitors at the advertised refresh rates requires me to create:
`/etc/udev/rules.d/61-mutter-preferred-primary-gpu.rules` with the following contents:

```
SUBSYSTEM==“drm”, ENV{DEVTYPE}==“drm_minor”, ENV{DEVNAME}==“/dev/dri/card0”, SUBSYSTEMS==“pci”, ATTRS{vendor}==“0x10de”, ATTRS{device}==“0x28a0”, TAG+=“mutter-device-preferred-primary”
```

Things have improved but the issue is still present on 580.82.09. It’s been over a year now. If it’s still not fixed in early 2026, I’ll switch my laptop to one with an AMD GPU. It seems Nvidia doesn’t care about its customers.

Yes this is also the issue I am having. I know in the past people complained about ‘general instability’ on wayland with nvidia cards and I don’t doubt that if you only have an nvidia card and nothing else in play that issues are fixed. But it seems like this specific subset of users with hybrid graphics with no mux switch are the ones still having issues. For me I have even figured out how to set each different GPU as the ‘primary’ GPU for wayland but then the monitor(s) hooked up to the ‘secondary’ GPU always have trash performance.
