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. http://farm3.static.flickr.com/2779/4062950845_ab86ca3dc4_b.jpg 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. http://farm3.static.flickr.com/2714/4062950949_c12dfaff3e_b.jpg 3. The characters in PCManX are truncated. http://farm3.static.flickr.com/2542/4062951027_8715e56332_b.jpg Following is my xorg.conf, is there any option that can work around this issue?
