There was an error starting the GNOME Settings Daemon.
Some things, such as themes, sounds, or background settings may not work correctly.
The last error message was:
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
GNOME will still try to restart the Settings Daemon next time you log in.
解决方法:
vi /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
前几天装错显卡驱动，屏幕反应慢
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
使用apt-get remove xorg-driver-fglrx 卸载ati显卡驱动和 apt-get remove xserver-xgl卸载掉安装错误的驱动就可以了
direct rendering: Yes
$glxgears ,2779 frames in 5.0 seconds = 792.983 FPS,跟fglrx差不多嘛
不过各种效果都能用了，忽然想起别人的问题，就是dns自动修改的问题，想要固定的话，在/etc/resolv.conf中设置好网关后，chattr +i /etc/resolv.conf，这样就不用担心，每次启动系统查找网络的时候去搜索信号，修改resolv.conf，导致部分不理解的兄弟上不了网，同样nm-applet 这样设置后，也可以加快系统启动速度，因为搜索网络是一个比较耗时的动作。
