So, I reinstalled Slackware and gave powerkit a try. I think it is a promising start, but I have a few comments and suggestions:
  1. Backlight controls are grayed out. I saw the note in the manpage about proper permissions being required (and the 90-backlight.rules file), but it wasn't clear to me what I needed to change.
  2. I'm not sure whether this is possible or not, but personally I use xautoset and i3lock instead of xscreensaver. It appears xscreensaver is required at least to detect when the machine is idle, but it would be nice to at least be able to set a custom command for the screen locking action. (Personally, that's a deal breaker for me, as I hate the xscreensaver lock screen.)
  3. It would also be nice to have an option to dim the screen after X minutes of inactivity.
  4. The inhibitors tab is blank for me with no buttons or apparent way to do anything.
  5. As a wish list thing: my personal power management scripts include an inhibitor based on CPU activity, which I find highly effective for overriding auto suspend. I have it set up to inhibit when CPU usage is 4% over at least 15 seconds, and then re-enable auto suspend when it is under 4% for 30 seconds. It would be awesome to have that in powerkit. I can share the code if you are interested.

hi, thanks this is useful to me in fluxbox as a drop in replacement to xfce4-power-manager - couldn't see the battery decay with xfce4-power-manager.
i don't know why the powerkit icon doesn't show up right away in the fluxbox tray, more reading needed.
suspend is actually really nice and quick on slackware :]

you can probably push the rc2 to the

Just got around to playing with this (rc2) and so far it does what I need it to (suspend to RAM).

Now I just need to go back through my notes and find my wake-from-USB stuff and my HTPC will finally be rid of Windows.

A question, is it qt5 compatible? I haven't tried, but since I already use qt5 I was just wondering.

A bit of nitpicking, maybe just for the sake of sanity. Should your SlackBuild copy the '90-backlight.rules' to the docdir, should it name it '90-backlight.rules.example'?

Very nice work. Thanks for making this!
