Failure to Suspend With Laptop Lid Closure After Upgrade to 22.04

[Carl Greco]

Dell XPS-15 9550 Laptop lid closure does not result in transition to Suspend mode following upgrade from 20.04 to 22.04. Screen remains on and hard disk does not spin down. If Suspend is enforced from the Power Off/Log Out option, disk remains on.
Attempted the following:
1. Edit the file /etc/systemd/logind.conf to uncomment the lines HandleLidSwitch=suspend, HandleLidSwithExternalPower=suspend, and HandleLidSwitchDocked=ignore. Did not result in Suspend mode when lid was closed.
2. Activated Standby Timeout Settings and set time to 5 minutes for the hard disk. The disk remained on.
Both gnome-power-manager and pm-utils are installed. Using X.Org X server

(you've filed this issue as being related to the upgrade process itself, ie. ubuntu-release-upgrader, which had completed it's job the moment you'd rebooted & logged into your machine.. suspend should not be done during the upgrade cycle... instead your issue appears to be post-upgrade - thus package change)

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Carl Greco (carl-greco)]

Suspend mode now activated with laptop lid closure following these change and a power down reboot.

Disks App - activated the Standby Timeout Setting

Uncommented the following lines in /etc/systemd/logind.conf

HandleLidSwitch=suspend
HandleLidSwitchExternalPower=suspend
HandleLidSwitchDocked=ignore

[Carl Greco (carl-greco)]

Suspend mode is not activated when laptop lid closed or when "Suspend" was selected from "Power Off/Log Out".

[Carl Greco (carl-greco)]

Reinstalling Ubuntu 22.04.1 and all the updates did not fix this issue. The laptop will go into suspend mode the first time the lid is closed after booting; however, it will not suspend on subsequent attempts. This suspend bug did not occur in Ubuntu 20.04.

[Carl Greco (carl-greco)]

Is my only option to fall back to 20.04?

[Carl Greco (carl-greco)]

Suspend was not routinely working. Appeared to be a brmcfmac issue. Please see attached tail from dmesg. I have created the file in /usr/lib/systemd/system-sleep/10-brcmfmac.sh from a comment by tobek in https://askubuntu.com/questions/935672/ubuntu-16-04-on-dell-xps-suspend-occasionally-fails

So far suspend has worked 3 of 3 attempts!
