Thank you for your answer. I solved the problem with nvidia prime not really disabling the nvidia card (still drawing power) when switching to Intel with:
sh -c 'echo auto > /sys/bus/pci/devices/0000\:01\:00.0/power/control' Almost halved the power draw on my Dell XPS 15. -- 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
