My Arch linux become faster after second reboot , why ?

Hello all!

I have a problem, after first boot all  applications work slow ( I use wmii as window manager ) , when I switch from one application to another  seems like nvidia driver does not work at all but nvidia-settings shows that nvidia driver loaded and direct rendering enabled.
After second boot everything is become fast. Where is the problem ?   

sys info:

Do you have your hostname set properly?

HOSTNAME in /etc/rc.conf should be set to something you want, and /etc/hosts should be like:

127.0.0.1 myhost.domain.org localhost.localdomain localhost myhost

With all instances of myhost replaced by youe hostname, and domain.org replaced by your domain name if you have one (if not, put whatever there).

EDIT: Okay, it's 3am, time to sleep... the above may be stupid, forgive me.

Is the 8400M GS an AGP card?

If yes there is an already known bug that that causes some AGP GPUs to be used in PCI compatibility mode. This only affects the first start. For me it works when I just log out and back again.

The bug is fixed in the latest beta driver found in the AUR (I'm waiting for an package in the offial repos, dunno why ;b )
