Yesterday I upgraded my Laptop’s mainboard, it all went fairly smoothly except that Ubuntu Linux is no-longer suspending when I close it. Does anyone have any ideas on why this might be?
If you were suspending to hibernation, this is a known problem. You will need to manually update your kernel to a newer one. However, if I am not mistaken, the LTS kernel saw some updates which fixed hibernation. I’m not sure though.
If you are referring to s2idle deep then I’m not sure. Have you already done a sudo apt udpate, and sudo apt full-upgrade?
If this is Ubuntu 22.10, this is a known lid event issue we’re working on. I’ve been recommending using the power off pull down menu to select Suspend.
Thank you all.
Not sure if this is related but:
ian@framework ~ > cat /sys/power/state freeze mem
Shouldn’t that include sleep/suspend/hibernate?
freeze mem disk
