Public bug reported:
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.
