玩Debian 7的家伙们别再操心驱动了，那个打补丁的驱动是纸糊的

装好X后，确认有这个包：xserver-xorg-video-fbdev
然后修改/etc/X11/xorg.conf为：
Section "Device"
Identifier "Configured Video Device"
Driver "fbdev"
Option "UseFBDev" "true"
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
DefaultDepth 16
SubSection "Display"
Depth 16
Modes "1024x600"
EndSubSection
EndSection
即可。测试发现性能没有能被感受到区别。
