After doing the above, several screens of text scrolled past during  
the boot process. I end up with a multi-color display at what appears  
to be a very low resolution and low color depth setting.

However, I could just make out the outline of a rectangle in the  
middle of the screen, which turned out to be the login window. When I  
type my password (blindly), the boot process continues and ends up at  
the desktop with the correct resolution, but still the wrong color  
depth.

Still, at this point I'm able to launch applications and windows  
normally. The color depth is low, but the resolution is correct and  
everything works correctly--Firefox, FXTerminal, etc.

Also, where will I find these logs you mentioned. I don't know where  
to look for them. Please excuse my ignorance, Linux is new to me.

When I tried the above boot parameters with the live iso, I ended up  
at a black screen, loaded with lines of text. I don't know how to  
capture this text, so I can't tell you what it said.
