Running hot while asleep
Anyone else having the strange problem of a System76 machine running hot with fans whenever the lid is closed?
It seems to have started after the latest PopOS update yesterday...

Do you have a dock connected? That seems to mess with sleep/suspend on quite a few machines.

I have this issue on my lemp10 ( no dGpu ) when it is connected to the dock. The dock prevents it from fully sleeping for some reason.

There is an issue in GitHub https://github.com/system76/firmware-open/issues/199
seems this is fairly common. Not sure how to make System76 give it a little more priority

Same here with my lemp10. Running hot when lid is closed, fans maxed out. Are you saying that a connected USB hub causes this to happen? Or what do you mean by “dock”?

By dock I mean the Plugable UD-CA1A which is listing on the System76 site as recommended. Mine doesn't run hot it just doesn't suspend and the fans run at a slow speed.

That occurred to me... but I'm pretty sure I haven't been loading up malware lately. :)

I don't have a dock connected. After restarting, I haven't got it to do it again. I may have failed to restart after the update yesterday and maybe that put it into some weird state where it wouldn't sleep.

Yeah. I know the pain as well.
- Ubuntu 20.04 with S76-PPA for firmware and driver
- When dock is connected (USB-C-Thunderbolt Dell TB19) then the problem of running hot (or not suspending) is present.
-When there is no dock then the suspend works and nothing runs hot.

Model, and does it have a dGPU?
My galp5 with the dGPU would do something similar when certain apps were running. For me, PyCharm and MS Teams were causing issues when launched using Hybrid mode and the dGPU. Nvidia driver would crash when going to sleep (or waking?) and require a reboot
lemp10 is the model. Checking on the dGPU.
Hmm, got a black screen twice after logging in. Finally up.
How do I check the GPU?
I would run `lspci | grep -iE 'graph|nvidia'` and check the output. For mine there's 2 different graphics adapters available, the integrated Intel chip, and the dedicated nvidia chip.
00:02.0 VGA compatible controller: Intel Corporation TigerLake GT2 [Iris Xe Graphics] (rev 01)23:00.0 3D controller: NVIDIA Corporation TU117M [GeForce GTX 1650 Ti Mobile] (rev a1)LemurPro 10 doesn't have a discrete GPU, only Intel Xe graphics.
Ah, ok, so that's not the issue. Thankfully it hasn't done it again. So hopefully it was a temporary thing related to my not restarting right after the update yesterday. Thanks for you help!
