I have just installed Ubuntu on both my laptop and my workstation.
My laptop is a somewhat older one, with a 2Ghz centrino Core 2 Duo processor, an NVidia GeForce Go 7300 graphics card, and 2 gigabytes of system RAM. Compiz+Emerald works flawless and super fast on this computer in every aspect.
My workstation is a dual core (not Core Duo) 2.5GHz system, with a 1GB GeForce 9500GT card and 4 gigabytes of system RAM. 3D performance with Compiz is super slow here though, and other operations feel heavy as well. Opening a new tab in Firefox for example takes a couple of seconds.
Both computers have the same driver version installed (173.14.28).
I am new to this OS, any suggestions on how I could improve performance on my workstation? Many thanks!
