I made a post about it a while ago:
The proprietary NVidia driver just handles it all fine. I think that this driver doesn't make stupid assumtions like the ATi ones..
<wrong>Fglrx can't be configured via xorg.conf, so it's a no-go :-(</wrong>
Fglrx crashes when trying to load more than one X-servers via the gdm configuration file.
Thanks for all the responses haven't checked the board since friday. Right now I have multi-seat working using fglrx. But, was just checking the status of the open source drivers, have had problems with them and multi-seat in the past. Thanks.
How did you get it working? I never managed to do it with fglrx!
