If your laptop is a HP pavillion dv4145EA as you said in the first post, you have an intel 900 embedded video card.
So open your xorg.conf file (after doing a backup) :
Code:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup
sudo gedit /etc/X11/xorg.conf
Then modify the corresponding sections to look like that (text in bold) :
Code:
Section "Device"
Identifier "Intel Corporation Intel Default Card"
Driver "i810"
BusID "PCI:0:2:0"
EndSection
Section "Device"
BoardName "915 GM"
BusID "PCI:0:2:0"
Driver "i810"
Identifier "Intel Corporation Intel Default Card"
VendorName "Intel"
EndSection
To test your 3D acceleration run this command : It will show you your FPS score, try it before and after the modification to see if you have improved your acceleration.
