After upgrading to plasma 6.7, i found that my fan is very loudly. I ran nvidia-smi and found that /usr/bin/kwin_wayland is running on NVIDIA GPU.
Anyone know how to slove it?
I wonder if KWIN_DISABLE_VULKAN would help. This seems to be part of the new Vulkan pipeline. I am OK with the dGPU running, as long as battery life is not destroyed. Doing nothing much, it says it is using 6W (using nvidia-smi). It would be nice to get some settings, like the ability to disable this when on battery etc.
Any luck finding out anything about this?
Do you know if there is a bug open?
I am also having this issue. I tried several environment variables but was unable to get plasma to run on the iGPU. This does significantly affect battery life. I would greatly appreciate if someone knows how to resolve this.
Kernel: 7.0.12-1-cachyos
Plasma Version: 6.7.0
Asus ROG Zephyrus G16 GU605MY
For reference, I tried adding a script to add the Environment Variables to: .config/plasma-workspace/env/set_gpu.sh
When I set KWIN_DRM_DEVICES to /dev/dri/card0 then most programs use the dGPU.
Setting /dev/dri/card1, only kwin_wayland uses the dGPU.
It is like kwin_wayland is ignoring the environment variable and always selecting the dGPU.
I misspoke in my first post, I had not set the correct environment variable in the correct location.
Adding a script such as:
.config/plasma-workspace/env/set_gpu.sh
in the format:
export KWIN_DISABLE_VULKAN=1
does resolve the issue in my local testing.
The problem must be with how the Vulkan implementation selects the GPU.
It is likely defaulting to the best available gpu, which would be the dGPU.
This would technically be fine, except when on battery this becomes a massive power drain that is not needed for most usage.
I found a relevant bug report：
I have the following errors in journal which reference my dGPU suggesting kwin is preferentially using this card over my iGPU (Intel HD Graphics 630) which also supports Vulkan. Either way kwin is using OpenGL and not Vulkan once loaded.

Jul 18 12:14:17 Machine kwin_wayland[711]: Device AMD Radeon RX Vega M GL Graphics (RADV VEGAM) misses required Vulkan extensions
Jul 18 12:14:17 Machine kwin_wayland[711]: VK_EXT_image_drm_format_modifier
Vulkan has extensions (like wayland has protocols) and your driver clearly does not implement one of the very few ones that KWin requires in order to make use of Vulkan, here VK_EXT_image_drm_format_modifier.
Still KWin does not require vulkan to use a GPU, it requires OpenGL ES only. KWin with vulkan allows some optimizations depending on the driver/GPU.
This message does not mean your iGPU is not used.
On my dGPU (Radeon RX Vega M GL) you are correct.
However the iGPU (Intel HD Graphics 630) does support it and kwin if I understand correctly should be trying to use this GPU first on a laptop anyway.
