gdm error

[Chocrates]

i just installed debian on a different computer that has a pci graphics card and onboard graphics
when i boot gdm throws an error about xorg.conf
now when i open xorg.conf the bus is that of the pci card but the name is that of the onboard graphics
i changed the name to that of the pci card and also changed it in the default screen
i also changed the driver to nvidia
now its saying that nvidia isn't found so im guessing i have to install drivers for that
any ideas if tahts the only thing left to do and if so where do i find info on installing nvidia drivers

Hi and Welcome !

Try "vesa" driver instead of "nvidia". In case it doesn't work, execute this

lspci | grep VGA

Post output here. Attach xorg.conf file here, if possible.

when i put the driver as vesa it starts up and then goes completely black
when lspci | grep VGA the output is
01:04.0 VGA compatible controller: nVidia Corporation NV18 [GeForce4 MX 440 AGP 8x]

as for the xorg.conf ill write out the parts that i think you are looking for, if you need all of it ill download a live distro and grab it.
to begin with the device section had

Section "Device"
Identifier "something something onboard graphics"
Driver "I810"
BusID "PCI:1:4:0"

all i have done is change the identifier to the nvidia one and messed with the driver

the confusing part is that the bus has always been that of the pci graphics card
