安裝Ubuntu8.04後，和7.10配置方法不同。比前是一個命令sudo dpkg-reconfigure xserver-xorg解決。現在不行了。
登錄後分辨率可以改，但那是個人設置，啟動xorg時的分辨率還是不合適。我的是17寸純平顯示器，看著半個屏幕很難受，字也看不清。
手動修改/etc/X11/xorg.conf吧，裡面連默認選項都沒有，都得手動添加。那就添吧。
剛開始只添加了水平和垂直掃描頻率（710時就只手動改這一項），重啟後竟然顯示找不到合適驅動，讓手動選擇或添加。暈
最後，到控制器終端用7.10的/etc/X11/xorg.conf覆蓋，一切OK。
什麼也不說了，把7.10的/etc/X11/xorg.conf貼出來，省得以後找不到
cat /etc/X11/xorg.conf
