I would like to try it out. I upgraded the system from Ubuntu 9.04 to 9.10. But after the upgrade, it is called a depressing one. The CPU usage of the Xorg process is always high, and the computer is almost stuck.

After Google for a long time, we finally found a perfect solution:Howto: jaunty Intel Graphics performance guide 

However, check the title. If you encounter a similar problem but not an Intel video card, I dare not say that this method can be used.

although the post is very long, you can do it step by step. We recommend that you choose safe Configuration solution or optimal * Configuration, the difference between the two is whether to upgrade the kernel. After using the old safe configuration solution, the high CPU usage problem is solved, however, desktop effects cannot be enabled (before upgrade to 9.10, ), So I simply The kernel is also upgraded, and everything goes well.

If you upgrade the kernel, it will remind you whether to overwrite the menu. to overwrite the LST file, make sure to back up the file before overwriting (for example, if you have installed a dual system and provided the boot menu by Linux, you may need to refer to the old menu. LST will modify it to start multiple systems. LST, Google, a lot of online)
