http://ubuntuforums.org – Hello, I'm running Ubuntu 12.04 x64 with the latest updates on my ASUS K53E. After a vanilla install of any ubuntu version, the K53E will not suspend properly. A script from here (http://thecodecentral.com/2011/01/18...ot-working-bug) fixes it right up. However, for the past few days I've been getting more severe PM problems. The system will lock up when rebooting, shutting down, suspending. It will start the process of shutting down/suspending, but then it will just go to a black screen. System and LCD still on, but a black unresponsive screen. Behavior identical to how suspend beh (Hardware)
