As the bug, very poor Xorg performance on various older graphics HW -
XAA solves this, described in the following link:

https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/363238

I enabled XAA option in xorg.conf. However, I got render errors in
some applications.
1. The system monitor only shows the top left cornor around the GMail
logo in the following picture.

2. With system monitor on the top, when I drag the program, Take
ScreenShot, the screen does not refresh correctly.
There are several ghost shadow left behind.

3. The characters in PCManX are truncated.

Following is my xorg.conf, is there any option that can work around this issue?

Option "RenderAccel" "off"
might help. XAA is getting more and more bitrotten. The real
solution will be to migrate to KMS.
