hi i am not the gdm author

to me this sounds immediately unrelated to gdm

apparently if you revert cards it will again start, and if that is so 
... then you have a debian question which is easily asked in debian 
forums (linuxquestions as well).  you apparently have a question of how 
to re-run the video card setup (to detect your card, which is an X.org 
question) from the a terminal prompt. (changing configs before changing 
cards was possible).  remember your "designing a system" when replacing 
hardware - having a custom system (ie, not an iPad) is not always 
automatic.  also i hope you checked if your new card is compatible with 
your X.org (if not, return it quickly)

good luck !
