You have been subscribed to a public bug: Recently upgraded (side by side install) from 22.04 (fully working daily driver OS) to 24.4.1. My normal environment is a Dell precision M6700 laptop on a docking station with an external USB keyboard and external DP LCD monitor. Always powered from AC. laptop lid is always shut.
Usual startup procedure as follows --> power on laptop via docking station power on button, (laptop boots grub2; hidden from view since lid is shut), eventually after 20 seconds DP monitor shows Ubuntu login prompt. I enter name\password and after 10 seconds get Ubuntu desktop on DP monitor. All well and good. However with 24.4.1 everything is the same up to the Ubuntu login prompt. After entering name\password the laptop then suspends\hibernates (fans stop, USB keyboard off, DP monitor no signal). If I then open the laptop lid slightly the laptop wakes up. Closing the laptop lid I get the logged in Ubuntu desktop on the DP monitor. How can I find out what is causing the laptop to go into suspend\hibernate following login when its lid is closed? No LSB modules are available.
