I have the same problem of power drains even when prime-select is on intel. I know for sure that the nvidia GPU is running because the external HDMI port is working and shouldn't since it's wired to the GPU.
sudo sh -c 'echo auto > /sys/bus/pci/devices/0000\:01\:00.0/power/control' sudo sh -c "echo "1" > remove" gives no result on my system (Nvidia Quadro M2000M/Thinkpad P51). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752053 Title: nvidia-390 fails to boot graphical display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1752053/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
