Power management not running after upgrade

[steve7233]

When running the energy saving configuration in system settings I got a message that said the Power Management configuration module could not be loaded.

Are you referring to the KCM module or something like laptop-tools?

Anyways, first step is to run

sudo apt-get update && sudo apt-get dist-upgrade

. Will probably require logging out and in. If that doesn't help then we can start looking more specifically at the problem.

+1 for Kubuntu 13.10 64b

[System Settings], [Power Management]:




so, then [Startup and Shutdown], [Service Manager]:



Any ideas?

Try the commands I recommended. Is this an upgraded install or fresh?

[steve7233]

I fixed this by running recovery mode. Some things didn’t finish configuring at the last part of the upgrade. The Power management works now. How about my Kernal panic thread?

Those commands are run as part of my post-installation configuration. So, no change there.

This is a fresh install.

Also, found this in dmesg output:

Hmm, this usually needs drilling down to fix but what I can recommend is adding "pcie_aspm=force" to your kernel boot options. It's not ideal but should work in most cases. Does this problem affect actual usage?

[teracow]

No, I don't usually leave this computer alone long enough for powersaving features to be useful. Just noticed the error when looking around and thought I should mention it.

I'll try your suggestion.

As a rule of thumb, you are almost inevitably going to get some ACPI warnings or errors. I get a few on my machine and it does not affect normal use. Even with these errors I get better battery life than under Win7 so it really is safe to ignore them. That said, the solution I passed onto you can - in some limited cases - have a few unintended consequences so I would rather just ignore the warnings and not try anything.

If you do feels your errors are impacting your use of the system feel free to let us know.

Okiedokie, I think I'll leave it alone then.

Thanks!
