After barely scratching the surface on my first day of using Ubuntu, I decided to start to get to know it deeper. You know, just like when you meet a hot girl and want to know more about her before you let her to sleep with you.
So, I started playing with all the settings and buttons I could find with Deedee's voice continually sounding in my head. I didn't think anything could go wrong (the presence of Deedee's voice could have suggested otherwise). I started going through the System > Preferences menu. But a hidden enemy was lurking in the dark waiting for the wrong move. And when I got to the Screensaver options it hit.

The cursor started moving in slow motion. First I thought it was some minor glitch. “Ah, it will recover in a sec” I said to myself. But after a few more seconds it completely froze. I was in denial. My Ubuntu can't die. It's ubercool and indestructible. Finally, it took me a minute to believe it. Ubuntu was stiff and I could hear the flatline.
Biiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiip.
I hit the Reset button and decided to try again and see if it was just an accident or really a bug. And it happened again only faster. The AntSpotlight screensaver hit swiftly injecting it's lethal venom and crashing Ubuntu.
It turns out this isn't something new. The bug was reported a few years ago and the problem is with my VGA card (Gigabyte K8M800/K8N800/K8N800A) and it's drivers. Now I can't run any 3D graphics. Tough!
