May well be that my USB-C hub, or my sys-usb qube, is to blame in my troubles with the Librem 14. Using everything straight off the laptop made it through a day of repeated Buildroot builds that flexed all my cores for more than an hour at a time.
@rbrown in my case the shutoffs happened while I was out of battery and thought I was charging but was not. That’s what led me down the am I charging or discharging path. My screen (hdmi through the usb-c hub) randomly shutting off may be due to the sys-usb qube OOM killing things so I bumped it up to a gig from 300M. Plan to use it that way today. Will let you know how that goes.
@ajmartinez ah i see. keep up with the updates :) I've been going back and forth with Qubes for a while so always good to see how its working on the L14 that I hope to use for a long time
@rbrown dom0 and sys-usb both see the hub disappear and reappear so I think it may just be some module instability. Will burn a live USB of PureOS and see what happens in that environment. My old laptop is also on QubesOS, and that’s really where I do most of the things where Qubes magic is really beneficial.
The audio jack doesn’t work at all in Qubes, but that was true of my T460s too. A USB audio device sorts that, and my headset came with one. The hub has one too. Both work.
@rbrown bumping up the RAM in sys-usb didn’t help, and I bounced the VM without checking dmesg and friends. When the screen goes dead over USB-C it also takes out charging which I believe contributed to my dead machine symptoms. At present I am just not using the USB-C hub with my Librem 14. It has enough native ports to suit my needs, but I may try just a dumb hub with no more than PD pass through and USB3.1 ports to see how that goes. Charging itself has not been a problem directly on the port
@ajmartinez Interesting. I read your post and noticed you mentioned abrupt shutoffs. I've had that problem with my L14 too, not connected to a hub or anything else or even working it hard. Happens more often on battery, don't remember it happening when plugged in yet
