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

[GeneralJo]

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 ?
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 ?
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 ?
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"

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.

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