[ale] X and desktop redraws

[James P. Kinney III]

Odds are the laptop is using shared RAM for the graphics. That lowers
the ram you have for the main system. Moving a window will take some CPU
muscle. You can reduce the RAM (in bios) that the graphics sub-system is
getting. Also, you may have loads of stuff running that is eating up
resources you don't need. 

The nvidia driver is good at delivering graphics to the screen, but it
takes some RAM to load the module. Also, ceck to see if the desktop
environment is "up to date". Gnome is particularly sluggish in window
moves sometimes. You may be able to reset the move specs to use
wireframe on moves and resizes to cut down of CPU requirements.
