So I've managed to get Xubuntu 11.10 running on my early 2011 15' MBP virtually flawlessly - pretty much everything is working as it should right now. There is one exception though (something that I'd be willing to overlook on my desktop, but not my laptop): sleep.
If I close the lid, the computer doesn't appear to make any attempt to go to sleep, the white light on the front stays lit for the entire time. The computer is still fully awake and functioning normally after opening the lid, just with the screensaver running.
If I manually put the computer to sleep through the menu, it just goes to the screensaver with the keyboard and trackpad usually becoming disabled (non-responsive) after that.
I'd appreciate any help, as I'd love to use Xubuntu more but simply can't if sleep isn't working.
Thanks in advance.
