Ubuntu and the auto update

The reason Ubuntu can be both fun and frustrating is that it offers a sharp learning curve at times.

I saw the nice little orange update star in the upper panel like I occasionally do, and clicked on it to do an auto update of my Compaq laptop. Everything went well, and I returned to work.
The next time I booted up my laptop, I saw a warning popup telling me that "Ubuntu is running in low-graphics mode".
There was a setting for me to manually set up my monitor/video card, but the settings there were not the most user friendly. As I'm not sure which settings applied to my particular laptop, I cancelled the manual setup and continued on into a generic 800X600 desktop.
I determined the problem to be the latest install update. It seems that the update decided to include the fglrx envy files, which I did not previously have installed. That screwed up my graphics settings at bootup.
I simply used Synaptic Package Manager to completely uninstall those drivers and then rebooted. Everything went back to the way it was before.
Lesson to learn is that whenever doing an auto update, double check all the files that are selected to update and uncheck those that definately don't belong on your particular system.
