I have top running in a terminal window and there are two processes running, Xorg and top. Xorg is using 18% of the cpu. If I open another window the percent goes into the 30s and 40s. I don't think this is normal. Going to System->Administration->Display I see that I have the correct hardware installed, nVidia 41.9. The Dell system profile reports that I have a NV42 card. The refresh rate in a terminal window annoyingly slow. HELP!
