Ubuntu Lucid Lynx 10.04: FireGL xorg.conf Thinkpad R50p

Problem: By default the xorg.conf FireGL 128MB radeon driver settings are slow settings

Solution: to get a faster behavior do edit /etc/X11/xorg.conf
(Update: use Driver “ati” for 3D, use “radeon” for better flashvideos)

# sudo nano /etc/X11/xorg.conf

and change radeon area to:
Section "Device"
VendorName  "ATI Technologies Inc"
BoardName   "M10 NT [FireGL Mobility T2]"
BusID       "PCI:1:0:0"
Option      "AGPMode" "4"
Option      "EnablePageFlip" "True"
Identifier      "ATI FireGL T2"
Driver          "radeon"
VideoRam        131072
Option          "UseFBDev"      "off"
Option          "MergedFB"      "off"
Option          "AGPMode"       "4"
Option          "AccelDFS"      "on"
Option          "DynamicClocks" "on"
Option          "XAANoOffscreenPixmaps" "true"
