[闲聊]意外发现提升nv显卡性能的方法

只要装上xserver-xgl就可以了
glxgears结果变成原来的两倍
compiz各项特效明显更流畅,还可以同时开firefox平滑滚动
连同阴影的问题也一起解决
至少在我的8400m gs上是这样的

但是在旧的intel板载显卡上效果正好相反,不知道怎么回事儿

nvidia自己都不看好XGL.
There is increasing interest in delivering a composited X desktop, and debate about what
driver model can best accelerate the compositing operations. Two candidate models are: 1)
the existing XFree86/X.Org DDX loadable driver framework, and 2) a replacement DDX
that uses OpenGL for its rendering and modesetting.
Candidate 1, the XFree86/X.Org DDX loadable driver framework, has been in use since the
release of XFree86 4.0 in March 2000, and is what both the XFree86 and X.Org X servers use
in shipping operating systems. In this framework, a hardware-specific driver is loaded and
performs the tasks of rendering and modesetting. The framework does not dictate how the
loaded driver performs these tasks.
Candidate 2, the X-on-OpenGL model, eliminates hardware-specific X drivers, and instead
uses OpenGL to perform all X rendering. The X server, as proposed in this model, also uses
the OpenGL driver to perform modesetting, through the EGL_MESA_screen_surface [1]
extension.
.............and make the case that the existing loadable driver model is
better suited for achieving our goals. Finally, we end with a roadmap for how to achieve a
production-quality composited X desktop.
no security measure is worth anything if an attacker has physical access to the machine

但是用xgl真的流畅很多
用aiglx的时候比板载显卡还卡,firefox尤其明显

另外,开了xgl以后,nvidia-settings里的设置好像都失效了
