But the nvidia GPU is never used used automatic : I always have only 1W consumption. I only have nvidia GPU working (and consumption about 10W) when using the prefix : __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia So nothing "on demand" but only manual switching. It seems that eamless/automatic switching was available in 435 driver. In nvidia-settings I don't have a PRIME Profiles as you can see on this doc : https://doc.ubuntu-fr.org/_media/nvidia-prime-profiles.jpg Here you can see another example with 435 driver and "On Demand" mode : https://www.reddit.com/r/Ubuntu/comments/deh01n/nvidia_on_demand/ You can see the three mode. For me "On Demand" should be automatic... as in windows and in 435 version. Nothing like this in the 450 driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895327 Title: PRIME Render Offload "On-Demand" not supported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-450/+bug/1895327/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
