Public bug reported:
What I expected to happen:
After pressing the Sleep button on the keyboard to suspend, waiting two minutes
and then pressing the power button to resume, I expected the laptop to return
to the state I was in before I suspended.
What happened instead:
When I attempt to resume my E6420 after suspending it, I can see the mouse
pointer, but it appears that the resume never completes. The screen stays
blank although it appears to be attempting to refresh the screen occasionally.
The only way to continue work appears to be to force it to shut down by holding
down the power button and then booting from scratch.
Rebooting using the reboot command works flawlessly.
I am running the latest bios (A19) and just updated all software using
the Software Updater.
The output from lsb_release -rd is:
Description: Ubuntu 13.04
Release: 13.04
I went through the DebuggingKernelSuspend procedure:
