Newly installed Kubuntu 9.04 on my Acer Aspire 4530 laptop (1.9 Ghz, 2GB RAM, nVidia GeForce 8200). Cursor movement, window-rendering, loading webpages and scrolling are all extremely slow.

When I run 'top' the most CPU intensive processes are Xorg (usually around 20-50% CPU) and Konqueror (~10% which I'm using right now). Desktop effects are turned off, and I haven't been able to find a thread regarding display lag of similar or such astounding magnitude.

I haven't tested video since there are some flashplayer driver problems I haven't worked out yet.

Please let me know if there's any more info that might make this problem clearer.
What could be going on?

Are you using the restricted drivers for the nvidia card?

My apologies, problem resolved by going:

Applications -> System -> Hardware Drivers

...and then installing the recommended nVidia driver. <self-slap>
