I have Ubuntu installed without issue, but it runs horribly slow. So even when I just move the mouse (pointer moves fast) and do a quick hover over the sidebar for firefox etc, it moves horribly slow. Like it canot catch up to itself. It will take 5 seconds for the hovered names to finish coming up.
Does not do this when the live CD loads, so I think it's a hard drive/backplane/controller issue. Perhaps drivers or something?
Things start slow etc... just overall sluggishness.
Why is this happening and how do I fix it?
