1.RHEL和FC都使用xorg。
2.DRM是Direct Rendering Manager。#支持DRI需要在内核中打开这一选项。
3.在xorg.conf文件中写入:- Section "Module"
- Load "extmod"
- Load "glx"
- [color="Red"]Load "dri"[/color]
- Load "dbe"
- Load "record"
- Load "xtrap"
- Load "type1"
- Load "freetype"
- EndSection
复制代码

复制代码 5.所支持的模块都在/sys/module目录下,REHL默认不提供内核源代码。
6.重复FC与REHL都使用xorg,都可以支持DRI。
7.nvidia和ait显卡大部份显卡都支持OpenGL和DRI技术。 |
