Acer Aspire Z5761 All-In-One always freezes on wake from Suspend?

[darkstrike]

Hi all - not sure if this is the right place to post this as this is my first time posting here, but I thought I'd try posting on the overarching Linux forum rather than the Mint / MX Linux and Linux Lite forums as I've not managed to get any help there.

I just installed the latest version of Linux Lite onto my older Acer Aspire Z5761 All-In-One PC. I'm not new to Linux (my daily driver laptop runs Linux Mint, my 'tinkering' laptop runs MX Linux and my HTPC runs Linux Mint as well) but this is my first time installing Linux Lite. I'm a tech. guy and do computer help and repairs as a side business, but I wouldn't call myself a 'Linux Guru'...fairly advanced user, maybe, but I'm not one of you folks that can do everything through Terminal!

Basically....the install went fine and everything works perfectly EXCEPT Sleep/Suspend. System specs:

When I put the machine to sleep, all is well - when I try to wake it up, all also SEEMS to go fine EXCEPT that within about 5-10 seconds of waking to the desktop, the entire system freezes and I have to do a hard restart...

I've reinstalled Linux Lite twice now to make sure it's not a corruption issue...still does the freezing thing both times. I also tried installing MX Linux to the hard drive and it has the same freeze-on-wake issue there too. I ALSO tried booting from a Linux Mint USB and then Suspend/Sleep from the Linux Mint USB.....same issue there too.

Trying different kernels didn't help....I didn't try it under Linux Lite, but under MX Linux I tried an older 4.9 kernel and a later 6.0 kernel and the freezing issue happened in those too.

I don't THINK it's the WiFi reconnecting because I've tried telling the machine (under Linux Lite anyway) to forget the network so the WiFi wasn't trying to connect on Wake but the freeze still happens...unless it's some sort of WiFi driver issue...?

It's frustrating because the machine works flawlessly otherwise! Yes, I know I could just set it to never go to sleep, but it's going to be going to an elderly friend of the family who doesn't have a lot of money but uses their computer a lot, so I would prefer to get Suspend/Sleep working correctly to save on their electrical bill...

Anybody have any ideas what would be going, where I could look to figure it out, or how I could go about get it working correctly?

Thanks!

This is not a solution. Someone thinking better than I may have a solution.

I just wanted to remark that shutting the screen off and letting the CPU idle (with that generation CPU) will consume very little electricity. They're amazing buggers these days and their ability to throttle back on the power consumption is pretty impressive. It's not like ye olde P4s which you could substitute for a floor heater.

But, someone here may have a real solution. I'm only here sparingly for the time being.

Yeah, I had another similar Gateway All-In-One that a friend owns that they run MX Linux on. Gateway is owned by Acer, so the board in that is basically a Gateway-specific variant of the same board in this Acer....he was having the same wake-from-Suspend issue I am having, but he just disabled Suspend and told the computer to shut the screen fully off when idle. It works, but still....it would be nice to get Suspend working fully correctly if possible!
