Changing video cards

[John T. Moran]

I'm fairly new to Linux and am trying to change a video card. I am using 
the onboard intel video on the MB and am trying to put in a gforce 
fx5700. When I install the card and boot, the x server won't start. It 
tells me something about the kernel and goes to a login prompt. I've 
used other distros and when I have done something similar, it usually 
pops up a screen during boot asking me about the hardware changes. 
Ubuntu didn't do that and at this point I am kinda lost in how to change 
out the card.

Any help would be greatly appreciated. Thanks.
