I found somethin here:
http://wiki.debian.org/Multi_Seat_Debian_HOWTO but it seems that this article is old, cuz it talks about gdm2.3 and squeeze brings gdm3 , as it says we must make changes in gdm.conf, but there is no gdm.conf in /etc/gdm anymore. also talks about xorg.conf which doesn't exist anymore .I searched for multiseat debian squeeze, but everythin I've gotten have been non-eng. may anyone help me? :'(
I want to share my PC with my partner in the office.
