* Messages for package x11-drivers/xf86-video-r128-6.8.0:

* This package will overwrite one or more files that may belong to other
* packages (see list below). You can use a command such as `portageq
* owners / <filename>` to identify the installed package that owns a
* file. If portageq reports that only one package owns a file then do
* NOT file a bug report. A bug report is only useful if it identifies at
* least two or more packages that are known to install the same file(s).
* If a collision occurs and you can not explain where the file came from
* then you should simply ignore the collision since there is not enough
* information to determine if a real problem exists. Please do NOT file
* a bug report at http://bugs.gentoo.org unless you report exactly which
* two packages install the same file(s). Once again, please do NOT file
* a bug report unless you have completely understood the above message.

我的make.conf使用的是~amd64,升级的时候出现错误，查了很多资料，没有办法解决，我用的是nvidia的显卡，显卡驱动也安装好了，我不太清楚，为什么会再安装ati的驱动阿。

这里说的很清楚。
