到底装ati还是radeon
xf86-video-ati就是radeon,和它相区别的是xf86-video-radeonhd
xf86-video-ati will work to some degree on Radeon chipsets up to X1950 (latest R500 chipsets). Radeons up to the 9200 series are fully featured, stable, and support full 2D and 3D acceleration. Radeons from 9500 to X1950 have full 2D acceleration, they provide satisfactory 3D acceleration as well, but it doesn't support all the features that the proprietary drivers do (like powersaving, even though it is implemented and in an immature stage). A full list of supported chipsets can be found here. But, it supports DRI1, RandR 1.2/1.3, EXA acceleration and Kernel-Mode-Setting (with the latest Linux kernel and libDRM versions).
For now, all cards from HD2xxx till the latest ones, are supported by xf86-video-ati, but for now, with 2D support only.
xf86-video-radeonhd is a driver for ATI R500 chipsets (Radeon X1000 series) and newer. It is written by Novell with specifications provided to the public by AMD. It does support RandR 1.2 and is pretty much a work in progress.
xf86-video-radeonhd不像xf86-video-ati支持范围那么广,相对更专精一些吧,现在确实还有一些问题,不过用compiz感觉radeonhd似乎更快些,虽然glxgears的结果(之前测试的)显示ati驱动的分数更高... |
