| magic_ninja_work | hey 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 power | 00:28 |
|---|---|---|
| magic_ninja_work | The 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_work | I'm not sure how to report it, or if it needs to be reported, even. | 00:30 |
| magic_ninja_work | So, 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_work | something 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_work | The 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 affect | 13:55 |
| magic_ninja_work | TJ-, 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_work | I'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 info | 13:59 |
| magic_ninja_work | In powertop. You have to run it as admin and let it go for a while. Sometimes an hour or more. | 14:00 |
| magic_ninja_work | looks like I'm just getting incorrect power reporting in general with the new driver. | 14:13 |
| magic_ninja_work | I'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 that | 14:14 |
| TJ- | I'd presume the power usage is at the USB level | 14:14 |
| TJ- | is autosuspend enabled for the device? | 14:14 |
| magic_ninja_work | Yea. No hibernation, though. | 14:14 |
| magic_ninja_work | No options for it anywhere. | 14:14 |
| magic_ninja_work | Part 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_work | But 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 |
| magic_ninja_work | *wireless NIC | 14:17 |
| karlthane | Trying 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 |
| lotuspsychje | lordcirth_: did you test this yet? ^ | 17:47 |
| lotuspsychje | karlthane: currently 19.10 testing is a bit slow.. havent tested this new feature myself | 17:51 |
| lotuspsychje | karlthane: i saw lordcirth_ was interested in this too, you might wanna talk about it when he's back | 17:51 |
| karlthane | lotuspsychje: Thank you. | 17:51 |
