兄弟们帮帮忙，看看到底怎么了：
以下是xorg日志中的几条警告信息：

(WW) intel: No matching Device section for instance (BusID PCI:0:2:1) found

(WW) intel(0): Bad V_BIOS checksum

(WW) intel(0): Register 0x61200 (PP_STATUS) changed from 0xc0000008 to 0xd000000a

Could not init font path element /usr/share/fonts/X11/cyrillic, removing from list!
Could not init font path element /var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType, removing from list!

比较奇怪的后边那两行，我已经在section file里删掉了，还是报错，难道不再xorg.conf里配置的，还有起其他位置
另外BusID我配置的是PCI:0:2:0，前段时间不小心升成sid了，xserver-xorg等被升级，平凡的黑屏，后来我把xserver降回去了到现在暂时没黑屏，但日志里有些消息不明白，想请教一下
谢谢各位了！！！
