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

[GeneralJo]

Hi all - 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 LL twice now to make sure it's not a corruption issue...still does the freezing thing both times. I don't THINK it's the WiFi reconnecting because I've tried forgetting 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...?

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!

within about 5-10 seconds of waking to the desktop, the entire system freezes

I know there's not a big time window to check, but does the computer appear to work ok during the 5-10 seconds ?

After the 10 seconds, what's the state of the freeze ?
Is it total or do things like the mouse pointer or Caps Lock key still respond  ?
Does the clock in the corner show the right time or is it stuck at a interesting time (e.g. sleep, wake or freeze)?
Does pressing Ctrl Alt F2 together do anything ?

Next time you do a sleep/wake/reboot cycle, make a careful note of the sleep time and the freeze time.

After the reboot open a terminal and run a command like this

Code:

journalctl --since "2023-02-21 11:30" --until "2023-02-21 11:40"

Replacing the date and times with your sleep and freeze values - add a bit of margin but don't include the reboot.

This will page through the system logs.  There will be a lot of stuff but you may pick up something.

During those 5-10 seconds after it wakes from Suspend, yes, it does seem to work fine! Cursor moves, I can open menus, etc...

After the 10 seconds, what's the state of the freeze ?

It seems to be a complete freeze...haven't tried Ctrl Alt F2, but I've tried Ctrl-ALt-Backspace and it didn't do anything...capslock doesn't work, clock seems to freeze, mouse cursor freezes.

Next time you do a sleep/wake/reboot cycle, make a careful note of the sleep time and the freeze time.

After the reboot open a terminal and run a command like this

Code:

journalctl --since "2023-02-21 11:30" --until "2023-02-21 11:40"

As for the log - I'll take a look the next time I have time - hopefully this weekend!
