magic_ninja_workhey everyone. I just upgraded to 19.10 today, installed the nvidia 435.21 drivers and I'm on an optimus setup with nvidia / intel. I noticed in the new version there was a couple funky things going on with power00:28
magic_ninja_workThe bluetooth on this laptop now uses 4-5W consistently and the ethernet port uses 3W even though nothing is plugged in. I went ahead and turned them both off to verify, but that wasnt' an issue before.00:29
magic_ninja_workI'm not sure how to report it, or if it needs to be reported, even.00:30
magic_ninja_workSo, is there any way to see why the bluetooth driver is using so much power? It wasn't the case before.13:47
magic_ninja_worksomething changed since 19.04. I'm willing to investigate and report it, but I'm not quite sure how. I have just confirmed that it is the bluetooth driver via powertop. 3-5W is what it tends to use.13:47
magic_ninja_workThe other thing here is that my ethernet port is using 1-3W and it isn't even plugged in. This stops if I disable that ethernet interface.13:49
TJ-magic_ninja_work: sounds like something ACPI would affect13:55
magic_ninja_workTJ-, I just did an upgrade to 19.10, but I have a pretty popular laptop model, and I'm thinking it may effect many other users.13:56
magic_ninja_workI'm just not sure how to go about tracing it down.13:56
TJ-magic_ninja_work: where do you see the wattage reported? I've never been able to get powertop to show that kind of info13:59
magic_ninja_workIn powertop. You have to run it as admin and let it go for a while. Sometimes an hour or more.14:00
magic_ninja_worklooks like I'm just getting incorrect power reporting in general with the new driver.14:13
magic_ninja_workI'm sure part of it is that the nvidia card can't power off.14:13
TJ-magic_ninja_work:  an hour? oh, no wonder!14:13
TJ-magic_ninja_work: shame it doesn't tell me that14:14
TJ-I'd presume the power usage is at the USB level14:14
TJ-is autosuspend enabled for the device?14:14
magic_ninja_workYea. No hibernation, though. 14:14
magic_ninja_workNo options for it anywhere.14:14
magic_ninja_workPart of it is that I'm using nvidia on-demand, so I lose a couple hours of battery life from that alone. I get like 8-10 hours with the card disabled completely.14:15
magic_ninja_workBut yea, too bad power management is a bit screwy on my wired NIC, bluetooth radio and I'm using like 5W on my wireless device as well.14:17

karlthaneTrying to test the ZFS on root install option but have not found that option in installer, cannot even manually create zfs filesystem in installer. What am I doing wrong?17:47
lotuspsychjelordcirth_: did you test this yet? ^17:47
lotuspsychjekarlthane: currently 19.10 testing is a bit slow.. havent tested this new feature myself17:51
lotuspsychjekarlthane: i saw lordcirth_ was interested in this too, you might wanna talk about it when he's back17:51
karlthanelotuspsychje: Thank you. 17:51
