现在每次关机都会有这个东西，很annoying
/var/run/gdm.pid doesn't exist, perhaps GDM isn't running
查了查，原来是我X11启动方法不对，我是照着Arch Linux Beginner Wiki搞得，其实上边有很多东西Out of date。按照上边的方法，gdm给放在etc/rc.conf的daemon里面了：
DAEMONS=(syslog-ng dbus !network cpufreq laptop-mode netfs
crond alsa acpid !net-profiles hal fam networkmanager gdm dhcdbd
vboxnet @sshd)
把它移走，现在我的rc.conf是：

# Use 'ifconfig -a' or 'ls /sys/class/net/' to see all available interfaces.

然后改变etc/inittab里的启动进程,现在我的inittab是：
# /etc/inittab
#
# Runlevels:
# 0 Halt
# 1(S) Single-user
# 2 Not used
# 3 Multi-user
# 4 Not used
# 5 X11
# 6 Reboot

# Boot to console

# Boot to X11

非常neat。用了arch确实因为解决问题对linux了解更深了，看似很麻烦，但是由于网上社区很活跃，其实很多东西只要google一下就能解决。估计用gentoo能学到更多把，呵呵，不过我觉得arch已经很合适了。
