I should also add that I've attempted a kernel upgrade and am now running 3.8.0-27 but this issue is still persistant. I've swapped back to LightDM which has also changed nothing in terms of suspend.
I've found that after booting, i'm able to suspend and resume successfully once, and then after that, when attempting to suspend my laptop, the screen goes black, and the backlight remains on, with the laptop not going into suspend (the power light does not swap to amber and start glowing, it stays green). When this happens, I must force power off the laptop by holding the power button for 10 seconds and then turning it on again. I've done a lot of research over the last week, and there seem to be quite a few forum posts and bugs open with regards to the suspend issues on Ubuntu 12.04+ with varying degrees of success on fixing it (Some people have custom scripts, others have kernel upgrades, others have no success with any of these fixes) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990129 Title: Suspend/Resume hangs and fails - Ubuntu 12.04LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/990129/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
