Comment 12 for bug 602029

Thanks for confirming. So that means that everything should be alright with the hardware. What kind of graphics card does this machine have? For information around your hardware it would be easiest if you could run "apport-collect -p xorg 602029", this will collect the necessary info.

As for finding the actual quirk(s) I'm afraid we need to get a little dirty. It's probably best if you run that from a live system, so that you avoid any data corruption on the hard disk from hard power cycles on failed attempts. What you need to do is to try running "pm-suspend --quirk-..." with each of the available quirks until you find one which gets you a good resume again. On a failure, reboot the machine. The set of available quirks is documented in "man pm-suspend", section "OPTIONS". For example:

  sudo pm-suspend --quirk-dpms-on

(obviously you don't need to try the radon quirks if you do not have a Radeon/ATI card).

Please note that it might also necessary to have more than one quirk, but let's try the single options first. Also, once you send your hardware data with apport-collect, I might be able to give you a more precise list of quirks to try, by comparing with similar models.
