@Pete: Yes, more recent kernels now can automatically power down the nvidia card off when it's not in use, so you don't need bbswitch anymore.
What's even more cool is that with the nvidia 435.21 driver and the version of X that comes with Ubuntu 19.10, you don't even need bumblebee any more: if you enable nvidia load-on-demand in nvidia-settings, you get an intel desktop with the nvidia card pretty much powered down but you can run any application using the nvidia card by exporting these variables first: export __NV_PRIME_RENDER_OFFLOAD=1 export __GLX_VENDOR_LIBRARY_NAME=nvidia Of course, when the application finishes, the kernel powers down the nvidia card again. VUlkan is also very cool: I export this variable as well to ensure it gets used for the nvidia card: export __VK_LAYER_NV_optimus=NVIDIA_only -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1758243 Title: bumblebee needs configuration changes to work with nvidia-driver-390 and libglvnd0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bumblebee/+bug/1758243/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
