I know others are posting specific questions about the ATI drivers, but to keep things clear I'm posting a new thread.

Having just upgraded through YaST to ati-fglrxG01-kmp-default and x11-video-fglrxG01 the login screen is pixelated (large blocks scattered diagonally). After I log in - (by fortune the cursor starts in my password field) - things seem fine by all appearances.

I have the ATI Mobility Radeon HD 2400 XT (M74 94C8) and the driver is "fglrx".

Why would a driver upgrade affect the login screen? What can I do to make it readable again? Thanks in advance for helping a "noobie". I'm so noobie I have to put noobie in quotes.
