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. Hardware First generation (2006) Intel MacBook Pro (Intel Core Duo, aka Yonah based processor) with an ATI Mbility Radeon X1600 video card.
