So, the subject pretty much says it all. MATE Power Manager will put the display to sleep and dim it, so that's working. I also get accurate battery levels and notifications when the level dips to critical. But both the "Put computer to sleep when inactive for:" and "When battery power is critically low" settings are seemingly ignored - is that a known issue? Suspend works fine when I manually call it from peppermint-logout, so what gives? I don't even know where to look to start pinpointing the problem...  :-\

Any assistance would be greatly appreciated!

Hi astrotrain, welcome the, Peppermint Forum.  I have the same annoying issue with both my, 64-bit Fujitsu Siemens AMILO li3710 Notebook and my, 32-bit Acer Aspire One ZG5 A110.  Is it a known issue?  The answer is yes.  Is it going to be fixed?  That's a whole new story  :-\.  All the power managers have some sort of issue attached to them.  The Mate Power Manager was chosen for Peppermint Six because it had the least amount of issues when tested on the available hardware.  The problem with these managers is, when it's fixed for one brand of computer, it breaks on three other brands.  It's just a no win situation unfortunately.  Maybe someday some bright spark will come up with the Universal Power Manager that just works.  Don't hold your breath waiting for that day though  ;D!  Does that at least give you an idea of what to expect from Power Managers - they're all broken one way or another  ;)!!

Hi astrotrain,

To continue with AndyInMokum's reply, I would add that this piece of software was not developed by Peppermint. Therefore, I assume it would be best to post or search the Mint forums to see what's being said there about it.

Thanks for the prompt replies, guys!

I found some workarounds (which I have yet to try) involving cli tools and the like - I was just hoping there would be an easy fix for Mate Power Manager since I don't like to spread functionality across multiple tools if it can be helped (for the sake of grace and efficiency and whatnot).

At least now I know I'm not the only one with this issue, and I can hack away without worrying about wasting my time. ;D

another option might be to uninstall mate-power-manager and try xfce4-power-manager in its place.

We switched from that because it had its own problems fore SOME people .. but it may be better for YOUR particular hardware.

That's what I was going to suggest, and it's actually what I'm using.

Code: [Select]
sudo apt-get remove --purge mate-power-manager
Code: [Select]
sudo apt-get install xfce4-power-manager
Then you have to go to Menu > Preferences > Default Applications for LXSession and make the change there.  Under the "Core Applications" tab, where it says "Power Manger," just change it from mate-power-manager to xfce4-power-manager and you'll be good to go:



After doing that, if you want to start it right away, you can either manually start it (for the first time only) or log out and back in to autostart it.

Switching to xfce4-power-manager fixed everything - suspend on idle and critical battery! Thanks!

FYI, for anyone having the same issue, I'm running Peppermint on an Acer Aspire One d255e.
