Fails to suspend

[brad haack]

Occasionally my laptop fails to suspend with a lid close. I always get this message in syslog or kernal.log:
kernel: [ 1947.276485] ACPI: button: The lid device is not compliant to SW_LID.
But it usually continues and suspends successfully. This time there was nothing in syslog, kern.log, or dmesg after the SW_LID message.
It also never locks the screen either, & this time there was a msg on the screen after I opened it up about failing to lock the screen.

I think this has been fixed by updating the OS to Xubuntu 21.10 (& associated kernel) & the Bios to 1.3.0. I also had to keep the sleep mode in s2idle
