Early MacBook Lubuntu Sleep Issue

[dbdjre0143]

Obligatory statement about knowing this is an early Intel machine, but also knowing this will be the best place to find help...

Now that we have that out of the way...

I'm working on setting up a MacBook 1,1 with 32-bit Lubuntu 18.04 LTS, and with some fiddling I've gotten everything working except suspend. When you try to suspend, the screen turns off, but the fans never shut off, and touching the trackpad reveals the login screen instantly, as if the only thing that was actually off was the screen.

I've tried to hunt down information about it, and found lots of info about newer MacBooks waking up immediately when put to sleep, (and even tried some of those solutions), but this really seems to be a completely different issue as it doesn't seem to ever actually go to sleep.

I was hoping that one of the Linux gurus around these parts would have an idea on what to do to debug this.

Thank you in advance!

Installing xfce4-power-manager (it doesn't install xfce) should give you a nice gui config tool with options for sleep/suspend etc. Give that a spin and see if it works out for you. You'll find it in the menu -> preferences -> power manager

@wicknix - xfce4-power-manager is installed already. It's not that it doesn't try to sleep, it just doesn't go "all the way" to sleep if you get what I mean. Sorry, I guess it's a little hard to describe. 😅 The behavior is the same whether clicking "Suspend" from the power menu or shutting the laptop.

I gotcha. Strange. I have since put Lion back on my 08 macbook for development of browsers, but it was previously running a variant of Debian called Bunsen Labs Linux. While i'm not sure about sleep, suspend/resume worked when closing/opening the lid. I even got the flashing light on the front just like in OS X. So, yeah, not sure what is required. My c2d mini is running 10.6 and 18.04, but i just have it set to turn off my monitor after 20 minutes idle as i don't want it to sleep and disconnect me from irc or interrupt a torrent or a large compile running in the background. Good luck on your quest.

Cheers

Thanks for the help @wicknix.

Just to give the final results of this, I messed around with it for a couple hours trying various things, but never had any success. Because it was a computer I was prepping for sale to a client the following day, I ended up just swapping the SSD into an otherwise-identical MacBook 2,1 I also had, and everything just worked in that machine.

I stuck another hard drive into that 1,1 and installed Snow Leopard back onto it afterward, and sleep works fine there so I have to assume there is some incompatibility or mis-configuration on Lubuntu for that specific hardware.
