Can't config X server

[c_g12]

I just installed RH7.1 and when I tried to run startx , it says Fatal server error: no screens found, fatal IO error 104.
When I ran Xconfigurator I selected Cirrus Logic GD543x driver, and 1mb of Vid Ram. I also selected No Clockchip Setting. When it tries to test this configuration, it says There is a problem with your X configuration...
I'm pretty sure I'm selecting the right drivers because when I ran SuperProbe it said my Chipset was Cirrus CL-GD5430/40 with 1024 kbytes of Memory. Is there anything I'm not doing???

What monitor settings do you have in place, and what monitor are you using?

I have a DataTrain DC529P 15", but it isn't listed, so I use the Custom Monitor Setting, Super VGA, 800x600@56Hz

Look in /etc/X11/XF86Config fil. Go down to near the end of the file to
the Screens section, and make sure you have an entry similar to this. It
will probably have more subsections with more modes and better Depth than
my crapy work box
here.

use xf86config to configure x. you won't get the best settings but once you get x started, you can use [b]XF86Setup to fine tune everything else.
