ubuntu下如何解决nvidia显卡驱动问题

       接触linux快一个多月，最初装了红旗，认识一个linux高手，给了我不少的启示，对linux也有了很大的兴趣，以至不想装window，以促使自己更好的学习linux，她也确实没让我失望，linux的确太优秀，可惜大多数国人都被microsoft给迷惑了，不愿去研究linux，实在是一种可悲。庆幸的是我认识了linux，我希望这将是我的一个转折点。
　　说来也奇怪，我的dell机器，大部分目前的linux版本，都无法装上，不过这也是个好机会，她让我几乎试遍了所有的流行的linux版本，至少也是学会了如何装linux了。redhat,fc,dm,slackware,ubuntu等都很不错，不过我的机子上暂时只能装ubuntu，这也是我暂时不理解dell的愿因，但很可能是我本身对linux了解太少的原因。
　　现在来对我学习linux一个月做个总结：先是学习如何装系统，当然现在装系统远远没有以前那么麻烦，几乎不用你做什么，的确很kiss，可惜我不认为这太好，做为一个学习计算机专业的我来说，隐藏太多的细节，对我们学习未必是件好事啊！我的鼠标是usb接口的，但和我的系统似乎有些不大兼容，听老手说可能是内核的问题，这我就没办法，只好放在日后在解决了，在就是我的显卡，一个月来屏幕一直有些闪，但直到今天 我才解决了这个问题，其实显卡驱动是装好了的，只是要在/etc/X11/xorg.conf下在配制一下就可以了，但对一个新手来说，要找出来肯定不是一件容易的事。在此我记录下我解决这个问题的详细过程：
 chenheng@chenheng ＃sudo apt-get install nvidai-glx-legacy                     ##安装显卡驱动：
 chenheng@chenheng#sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_old ##备份是一个习惯：
 chenheng@chenheng#sudo vi xorg.conf

        # /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg
