[newbie] ATI XPERT 98 card

[Christopher]

Hello all,      I, myself, also just installed an ATI card, but mine is the XPERT 98 version.  It too, is listed in the list of video cards to select from.  It gave me the option to change the resolution (the reason I bought the card to start with because the internal version left me stuck at 800 X 600).  The monitor, 17 inches, is brand new as well.  I chose the 1024 X 768 resolution and style for the monitor.  Linux rebooted itself, and I no longer see my graphical interface showing the accounts I setup to log on with, along with what GUI I wanted to use.  I'm at a black screen prompt asking for login name.  How do I bring my graphical log in method back?     Note:  It did say that "your card will work well with 3D using this version..." and "will work well with 2D with this version..." - "which one do you want?"  I chose the 2D version.  It also said, "I can auto load X Windows for you - yes or no."  I told it yes.    Thanks for your time,     Christopher.
