我的显卡是nvidia6150的， 我按照google里的把ubuntu自带的驱动卸载干净了 ！ 安后下载NV官方的驱动编译安装一切OK（修改过xorg.conf） 启动后也能进去3D 。 奇怪的是我点系统里的那个重启然后输入帐号密码然后屏幕就一直黄色背景还有鼠标，就进不去了。 可是安主机的那个启动按钮直接启动就能进去我＃3，另外NTFS的分区也挂不上了 我改过fstab恩 在没装去驱动的时候能挂上
谁知道怎么弄的阿！！！！！ 我把xorg.conf和fstab发下 牛人帮我汾西汾西
# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by failsafeDexconf, using
# values from the debconf database and some overrides to use vesa mode.
#
# You should use dexconf or another such tool for creating a "real" xorg.conf
# For example:
# sudo dpkg-reconfigure -phigh xserver-xorg
