GDM not starting at boot

[amar_]

Hello all

I have this weird problem with Xorg on fresh installation.. I put gdm as login manager in /etc/conf.d/xdm and did rc-update add xdm default. However i am geting error with something like:

Device section "Configured Video Device" must have a Driver line

Fatal server error:
no screens found

However if I loog in as root and do /etc/init.d/xdm restart GDM starts just fine and i am able to log into Gnome. So there must be something i am doing wrong since X seems OK but it just fail to start on boot. Any advices ?

Try running Xorg --configure (or -configure, 1 or 2 dashes, I forget which) as root and using that xorg.conf as a normal user.

Also, post your emerge --info, existing xorg.conf (or tell us if you were using automatic conf), and /var/log/Xorg.0.log.
