Choppy Video display.
 

Hey Guys:

I have a Intel Corporation Mobile 945GM/GMS integrated video card in my Gateway laptop and the video is just terrible for some reason. When I use the scroll feature everything is choppy and slow. I looked at my xorg.config file and it all looks very generic.

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

Can someone please tell me how to verify I'm using the best video driver?

00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller [8086:27a2] (rev 03)

The driver for the Intel 9xx is called "i810". You can try adding to the "Device" section of your xorg.conf.

This requires the package 'xserver-xorg-video-i810' to be installed if it's not already. You might also want to add a VideoRam line in there also so you can utilize all your VRAM (since it's shared with the system memory and defaults to a low amount -- something like 8MB)

eg. for 128MB:
