Ok, i realize I am not the only one, but I will try to provide all info possible to make it exemplary as possible and narrow down the error sources.

I have a fresh install of Ubuntu 12.04 and the suspend worked fine upon having it freshly installed but now it does not anymore.

The suspend option from the system power button on the top right works fine.

Things I did do which I don't know if they are related:

  • Install and remove againthe FGLRX drivers (Radeon graphic card)
  • Install Jupiter power managment (shutting it down is not changin anything)
  • Plug in and out an external display

The configuration I know of is well set:

  • In System Settings/Power all is set to suspend when closing lid
  • Double checked with dconf-editor, everything set to suspend

So, from here on I don't know how to proceed.. what are common problems that cause this error?

EDIT: My computer model is: Samsung Series 5 14" NP530U4BI

Yes I'm experiencing the same issue with my Acer Aspire 7535G with a Radeon graphics card as well. This is the bug report I have issued: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/989674 Keep an eye on it for possible fix or support in the future.

In the time being do what I do to wake it back to GUI. Hit Ctrl + Alt + F6 to open a Ttyl terminal then hit Ctrl + Alt + F7 to reload the GUI.

Hope that helps!

  • my problem is somewhat different as the suspend option works perfectly but is just not invoked when i close the lid.. frustrating :-)
