Source: http://pm-utils.freedesktop.org/wiki/ "We include some basic power management hooks. The individual hooks can conflict with the ones provided by the laptop-mode-tools scripts, so you should either just remove laptop-mode-tools entirely or pick and choose between which package should handle what powersaving functionality. More hooks to handle powersave functionality we do not currently handle are welcome, provided they are general enough to apply across a wide range of use cases."

Make sure both are not installed at the same time.
This is now expressed as a !app-laptop/laptop-mode-tools blocker in pm-utils-1.4.1.ebuild, but that's far from optimal. We need to figure a way to strip latest laptop-mode-tools ebuild from the pieces that conflict with pm-utils, and remove the blocker. Unfortunately I haven't found any specific information about this yet...

I believe this "fix" does not fix anything, upstream is talking about power.d directory, not sleep.d directory. That upstream note about doubling functionality refers to the laptop-mode hook in the /usr/lib/pm-utils/power.d/ directory which is run by the pm-powersave script, but that files/laptop-mode-tools-1.55-pm-utils-1.4.0.patch deals with the hook in the hook in the /usr/lib/pm-utils/sleep.d And pm-utils don't provide any 99laptop-mode hook in the sleep.d directory anymore, so unless we let laptop-mode-tools to install its 01laptop-mode hook into the sleep.d directory, there will be no attempt to recheck the power state after resuming in a different power state. Proposed resolution: unless pm-powersave is run at the same time as laptop-mode (which is unlikely), these two packages don't conflict, it may be a good idea to warn the users that they should blacklist the offending hook in power.d if the plan to run both scripts at once the patch in laptop-mode-tools-1.55-r1 results in loss of functionality, so remove that please
Ok, so I was playing around with the pm-utils and laptop-mode-tools combo and I noticed that my HDPARM values set by laptop-mode-tools are disregarded. It turns out that by default /usr/lib/pm-utils/sleep.d/ contains the 00powersave script which runs the pm-powersave script upon resume from sleep/hibernate. The pm-powersave script then runs all the scripts in /usr/lib/pm-utils/power.d/, among which are all those offending hooks which then override settings from laptop-mode-tools. Proposed resolution: ------------------- Luckily, pm-utils implements an easy blacklisting system, so the solution is to put a file called e.g. laptop-mode-tools into /etc/pm/conf.d/ which contains a line definign the variable HOOK_BLACKLIST. This variable is accumulative and concatenated from all files within the /etc/pm/conf.d/ directory (including the file gentoo that is there by default). Now the question is what should be blacklisted, either the 00powersave hook which would prevent pm-powersave from running, or just the offending scripts in the /usr/lib/pm-utils/power.d/ directory, e.g. intel-audio-powersave, harddrive, laptop-mode, wireless, ... I vote for blacklisting the 00powersave hook, because blacklisting only the offending hooks would be hard to maintain in the long-term and we would have to blacklist nearly all those scripts. I suggest adding this in the next revbump of laptop-mode-tools which should be rev 1 once bug 396703 is fixed as I believe (and have tested on my setup) that these two fixes don't collide.
Created attachment 298651 [details, diff] patch for laptop-mode-tool-1.60-r1.ebuild This patch contains ATM both fixes for the next revbump, for bug 39703 (src_prepare part) and the fix for this bug (the src_install part). The laptop-mode-tools.pmutils file will be uploaded next.

Created attachment 298653 [details] laptop-mode-tools file to go into /etc/pm/conf.d/ This is the file that should be put into /etc/pm/conf.d/ to blacklist the offending 00powersave hook. As I said in previous comments, blacklisting the hook may be an overkill, but I don't have the time (and IMHO it's not worth it) to check if only some hooks in /usr/lib/pm-utils/power.d/ conflict.
