[Relevant specifications: Ubuntu 12.04 Precise Pangolin, Acer Aspire 5520, Nvidia GeForce 7000M/nForce 610M, Nvidia driver 302.07]
When I first started running Ubuntu a month ago, the video was screwed up (low resolution, console mode illegible). I eventually attempted to remedy this by installing the Nvidia drivers, and was successful. About ten days ago, I followed the Software Update recommendations to install the kernel updates, and the video broke (low resolution, Unity mode illegible). I was able to reinstall the Nvidia drivers (with some difficulty this time), and now the video is good again.
I am being offered another kernel update, and of course I am reluctant to install it. I only recently found out about the Nouveau drivers that apparently come with Ubuntu.
So my question is: Is there a reliable way to update the kernel as recommended without screwing up the video?
