Steps to reproduce
Suspend Scenario:
>From the Unity desktop in the corner up & right, select suspend.
Seems to reach suspend state.
Hibernate Scenario:
>From within the login GDM replacement, select hibernate.
It seems to reach hibernation.
Undesired results
When pressing the power, a noise as if awakening from suspend or hibernation
occurs, but results in an anticlimactic black screen.
I´m able to get into a term using cntrl+alt+FnX, but soon (a second or
so in) the screen freezes in term (showing only the text based login
line command prompt ) --perhaps after trying to get back to X
(cntrl+alt+Fn7).
Unplugging external peripheries does not interrupt the freeze. nor does
replugging an external PS/2 keyboard I use with a to-USB adapter. Both
the internal and external keyboards are locked out (no green light caps-
lock light indicator) and sysreq commands seem useless.
I have not tried unplugging the power adapter nor the ethernet cable.
Pressing the power button for 3 or 4 seconds does a hard reboot.
Expected results
I expect a successful & stateful return into my desktop, with both suspend and
hibernate functions, if not timely --as prior to my upgrade from Natty. I
expect this to be a kernel issue, as the problem seems to arise after
suspend/hiberate mode has been reached. Launchpad seems to have added this bug
as an ati video driver issue. Perhaps the video driver is not re-initiating.
Both modes worked on Natty out of the box, and continued to work with
more or less the same apps. To clarify, I have not installed software
that might affect functionality (unless you consider audio software such
as Listen, Exaile, or Quod Libet potentially dangerous).
The only change I have made to the power settings is (if I recall) is to
enable ¨suspend when inactive for 10 minutes on battery¨, which
shouldn´t matter since I never unplug the power adapter, anyway.
