请问手提Intel i855 主板自带的显卡是不是不能开启模糊(blur windows)和水纹(water effect)特效?

其他3D效果基本都能实现,现在就是差这两个特效不能工作。

:(

按道理是可以的,你们为什么总喜欢特效呢,华而不实用啊。

一部分特效是显摆的,但有一部分特效的确非常实用.

应该怎么做啊?找到了一些资料,但还是不知道怎么做

http://forum.compiz-fusion.org/showthre ... intel+blur

Because a lot of people have been asking about why they can't get Blur, Reflection or Water to work properly on their Intel graphics cards, I'd just like to fill everyone in on what is going on so that we don't get too many posts about this.

Essentially, after the fragment interface was added, it seemed to have broken support for fragment environment variables on Intel chipsets in indirect mode, which is needed for cool fragment_program effects like water distortion / blur / reflection. The workaround to make this stuff work is to use XGL. Below is a list of what works and what doesn't.

Intel with AiGLX
What works:
    Color filter
    Negative
    Color Opacity (fakeargb)
    Water, without the distortion effect (ie. the ripples are an overlay, not distorting the pixels underneath)
    Direct OpenGL Rendering, but rendered to the framebuffer, causing flickering. There is a fix coming out for this soon - see this
    Accelerated, but not properly redirected XVideo; change outputs from Xv to X11/XShm/XImage.

Intel with Xgl
What works:
    Color filter
    Negative
    Color Opacity (fakeargb)
    Water, with the distortion effect (ie. the ripples distort the pixels they touch)*
    Blur, only some parts:*
Gaussian won't work because of the lack of FrameBuffer_Objects
4xBilinear works for focus blur, but not for alpha blur (partial blur, but weird distortion on older X Servers, incredibly slow due to a problem with Mesa kicking compiz into software rendering)*
Mipmap seems to crash compiz

    Reflections work fine*
    OpenGL is redirected, but not accelerated
    Xvideo is redirected, but not accelerated

Just a note: because these are driver and DRI problems, we can't fix them (they need to be fixed by the developers of those components, which are separate from Compiz). Hopefully, this will be done in the next revision of the Intel driver.

Hope that helped.

For those of you who are using the Master Branch of Compiz Fusion, there is a workaround in the workarounds plugin, called 'AIGLX Fragment Parameter Fix'. Checking this will essentially bring the 'fixes' marked with a star in XGL over to AIGLX. Note that it isn't present in the Compiz-0.6.2 branch.
