Ubuntu 9.04 显卡性能不佳问题的解决

Ubuntu 9.04 显卡性能不佳问题的解决

环境：Ubuntu 9.04

我的笔记本的Intel集成显卡的型号是Intel Cooperation Mobile 945GM。如果完全按照上面的方法配置会导致播放电影是屏幕定住(freeze)，鼠标和键盘都不响应(SysReq都不起作用)。我把原xorg.conf配置文件中的

Option “AccelMethod” “UXA” 
Option “AccelMethod” “UXA”

去掉之后，这个问题就解决了。

但还有另一个问题，就是我按Ctrl+Alt+Fx(x=1,2,...,6)不能切换到其他的终端。目前这个问题还没解决。

附：

I believe a lot folks have the same problem as I have  -  the performance of intel graphic card is very low in ubuntu 9.04.

Some people say enabling UXA can solve the problem. But I found UXA is very unstable.

What you are expected to do is to update the kernel to 2.6.30 or later version.

Choose one version here.

http://kernel.ubuntu.com/~kernel-ppa/mainline/

download and install the packages in order as below

linux-headers-2.6.30-020630_2.6.30-020630_all.deb
linux-headers-2.6.30-020630rc5-generic_2.6.30-020630_i386.deb
linux-image-2.6.30-020630rc5-generic_2.6.30-020630_i386.deb

then reboot your system.
