I've an older MacBook pro (Mid 2009) dual booting OSX and Ubuntu. I really like coding and testing on Ubuntu, However, Often the screen freezes where nothing will work while I'm performing simple tasks like playing music or web browsing (I haven't seen any correlation to a specific program). The mouse will move, But it can't interact with the windows and the keyboard doesn't do anything. I am using Gnome shell currently, But I've been having this problem for long before I installed that.
Is there something I'm doing wrong to cause this?
