Tested with Dell XPS 9560 and Ubuntu 18.04. After installing the proposed packages and rebooting, everything booted correctly, although the nvidia driver was still loaded (I had my system set to use intel) and power use was quite high (~23W).
*But* after following the test case steps and switching to nvidia, reboot and then back to intel (after logout+login), everything seems good - the nvidia module isn't loaded, powertop reports ~12W and as a bonus reboot/shutdown is much faster (used to stall waiting for something GPUish). Definitely much better than the LTS experience so far. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1778011 Title: SRU: PRIME Power Saving mode draws too much power To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1778011/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
