thanks but on this laptop GhostBSD 4 don't work.
I have used one DVD and one usb key but I cannot use X as a user.
I can modify /etc/X11/xorg.conf but X start only as root.
If I log as a user (ghostbsd) X don't start and the message is:
Failed to executa the process "usr/local/bin/startx"
exec : Exec format error
The file "usr/local/bin/startx" is marked as an executable but could not be run by the operating system
I come back to plain FreeBSD on this machine
