Interestingly, in GNOME, you don’t even need to enter any commands in the launch parameters for games to forcefully use Nvidia instead of Intel. Additionally, if you connect the laptop to an external monitor, this error does not occur in KDE, as Nvidia is used directly, as far as I understand. If you enable the nvidia-persistenced daemon by running: "sudo systemctl enable nvidia-persistenced --now", it seems to resolve this issue. Additionally, you no longer need to add "__NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia" to the launch parameters to force games to use the Nvidia GPU instead of Intel. However, I don't fully understand the exact purpose of this daemon. Moreover, it's not required in other desktop environments, where it's disabled by default. If this isn't a KDE-specific issue, I'd like to understand where to look for answers and who I can reach out to for help. Thank you. > However, I don't fully understand the exact purpose of this daemon. Moreover, it's not required in other desktop environments, where it's disabled by default. It is required by the NVidia driver for suspend. I'm not sure either what's going on here, but I think the best place you could get answers is https://forums.developer.nvidia.com/c/gpu-graphics/linux (In reply to Zamundaaa from comment #6) > > However, I don't fully understand the exact purpose of this daemon.

Are you sure the report should be closed? Yes. KWin doesn't really have anything to do with Flatpak or what the Vulkan driver is doing under the hood. |
