Modular X installation results

[Dennis Jacobfeuerborn]

The upgrade to modular X went pretty well for me except for the fact that I 
had to install the package "xorg-x11-xauth" manually because the yum update 
apparently didn't pick that up.

What I immediately after reboot though was how slow my desktop has become. 
Moving around a window on the desktop is now very jerky. Before I saw the 
usual gtk refresh artifacts but the movement of the window itself was 
smooth. I have DRI disabled because I don't care about 3D and here is the 
device config I'm running right now:

Section "Device"
         Identifier  "Videocard0"
         Driver      "radeon"
         VendorName  "Videocard vendor"
         BoardName   "ATI Radeon 9500 Pro"
#       Option      "RenderAccel" "on"
#       Option      "EnablePageFlip" "on"
#       Option      "BackingStore" "on"
EndSection

According to the log XAA is enabled:
