Public bug reported:
I have Ubuntu 12.10 installed on my Dell Inspiron M5010 Core i3 machine.
When I use pm-hibernate, the computer hibernates successfully, and when
resuming it, the process completes to 100%, but after that nothing seems to
happen, and I stay in the black-and-white text mode screen without any further
activity.
On an attempt to escape this apparent freeze, I tried to press the magic
sequence <ALT><SysRq> + i, and to my surprise, graphics mode is back again to
the same state before hibernation just like one would expect from a normal
resume.
I tried the whole sequence again with <ALT><SysRq> + e, and the same thing
happened (resume completes only after the key combination is pressed).
Actually I am not sure the bug is caused by pm-utils, because after the key
combination is pressed, everything seems to be normal, which means that
pm-hibernate did it's job, but for now, it is the most relevant package as far
as I
can tell.
If you need any further info or testing that may be helpful, I'm willing to
cooperate.
