I'm a bit of an Ubuntu newbie. I just installed Ubuntu 12.04 on my Dell Inspiron 15R (M5010) and the graphics either doesn't load normal Ubuntu, or simply takes ages to load the desktop (ridiculous amount of time like 45 minutes to load an unresponsive desktop) so I choose to log into Ubuntu 2D. I install all proprietary drivers including normal FGLRX graphics, but that doesn't solve the problem. Now I get an error installing the post-release updates. It tells me to check /var/log/jockey.log but I've no idea what that log is saying. Any help please?
