		I have had issues with my screen freezing after coming out of sleep mode. The situation has become so bad that I am now dual booting with another distro (Linux Mint) and have to resort to using that instead. The only way I can use LL is to power up from scratch. I don't want to kiss LL goodbye, can somebody suggest a remedy please? Should I wait until LL 3.0 is released? Can I upgrade over LL 2.8 - I read somewhere that is not possible. That being the case, what's the best alternative? 
Thanks
Paul

		I think I've found the culprit of my problems - Compton compositing manager. I haven't had much success with compositing managers - Compiz was just as bad. I'd be interested to know if others have had similar issues. I removed it and voilà!
If anybody can suggest another alternative compositing manager for LL 2.8, I'm all ears.
