[Bug 1375173] Re: [Acer AO722] suspend/resume failure

 

Although I do recall suspend issues on this hardware with 14.04, I no
longer have any installations prior to 14.10 on which to test. Therefore
I am not sure if I can help with regression. However I would be happy to
assist with parsing the scope down to determine if there are driver
fixes that could resolve this issue 100% of the time on 14.10.

Christoper (or colleagues), could you please advise where I can find
instructions to help me do this. Thanks, Artemgy

Title:
  [Acer AO722] suspend/resume failure

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Lubuntu 14.10 Beta 2 newly installed
  * Close laptop lid to put system into suspend mode and power indicator changes from blue to slow flashing orange, indicating that hardware has entered suspend mode.
  * Reopen laptop lid and press a key to wake up, power indicator changes back to steady blue indicating that system is coming back up into full power state.

  HOWEVER screen remains completely blank (no backlight) and system
  appears totally unresponsive (although difficult to tell with no
  screen).

  * Attempted to use hardware function keys to activate screen - nothing.
  * Tried ALT-CTRL-F1 then ALT-CTRL-F7 to wake up X, still no display.
  * Attempted single press of power button to initiate "Shutdown" - no respone
  The only way to procede was to hold the power button for four seconds to kill power and start cold
