Issue/Bug Description:

On Fedora Silverblue, I'm trying to install system76-acpi-dkms package for better power management. Package installation fails with errors:

Steps to reproduce (if you know):

I use the following command:

rpm-ostree install --allow-inactive --idempotent --unchanged-exit-77 \
    system76-driver firmware-manager system76-keyboard-configurator system76-dkms system76-acpi-dkms

Expected behavior:

I expect to be able to install the package and have better power management.

Please see related issues like: coreos/rpm-ostree#1091

[jackpot51]

I don't know if it can currently be solved without building your own rpm-ostree install using rpm-ostree compose

Hi @jackpot51 ,

When I look at the documentation here, I see that DKMS is needed for proprietary firmware systems which I actually don't think that I have. I've a Lemur Pro with coreboot and I'm not sure whether I need dkms modules or not. Before installing Fedora, I checked whether I have these packages on Pop!_OS and I had them installed. So can you please clarify whether a Lemur Pro would need these?

[jackpot51]

@tunix a Lemur Pro will have all necessary kernel functionality in the system76_acpi module, which is included in the Fedora 35 kernel.

[tunix]

Does that include fan related stuff? I can't see any fan related information in vitals extension nor in the output of sensors command.

[jackpot51]

What kernal version do you have?

[tunix]

What kernal version do you have?

$ uname -a

[jackpot51]

What is the output of:

sudo dmesg | grep -i system76

[tunix]

$ sudo dmesg | grep -i system76
[    0.000000] DMI: System76 Lemur Pro/Lemur Pro, BIOS 2022-01-06_c73e482 01/05/2022

[njam]

@jackpot51 so fan control for 'Lemur Pro' is available in upstream linux? If yes, starting from which version?

My system76-power log shows this error:

[ERROR] fan daemon: platform hwmon not found

I'm running the latest stable Linux kernel 5.18.11

[curiousercreative]

I'm unaware of userspace fan control for any open-firmware System76 laptops. There are a number of issues relating to this shortcoming including this one

[jackpot51]

@njam system76-power only controls fans on Thelio desktops. That message is not important on a Lemur Pro.
