linux安装其实很简单，多装几次所有版本你也都会了。但经常会有显卡等不支持的情况。我装过好几次，也给别人装过好几次，常遇到的问题有：

1、根本就装不上。

我当初装过64位的ubuntu，一装就重启，不给你一点余地。我的处理器是64位的但不之为什么不支持。还装过红旗等，一到分区那里就重启……有位同学裝ubuntu，suse，fc7，红旗都装不上，一装到进度条那里就停了，我都无奈了，也不知改怎么办

2、显示不好。

我还装过fc，但现开始显卡识别不了，后来界面分成了上下两部分，好奇怪，装好了后也是这样。

只得改配置。／etc／X11／conf.org  要参照别人的改，还要有备份！分辨率也是在这里改,系统有默认的显卡配置，显卡驱动最好装上，但我还没装好……汗！

3、提示找不到acpi

这需要关闭bois里的acpi，但还会有问题。我给我一个朋友这样装好了，关机的时候关不了，重启可以，重启后有进不了windows，必须再把acpi改回来，真令人郁闷

下面是我刚装的ubuntu7。04 和fc6，xorg。conf的配置，(我有三个系统)_______________________________________________________________________________________________
