I have an nvidia geforce go 7300 card on acer 4230 travelmate.I use nvidia-glx-new driver and Hardy Heron.My computer starts with compiz but when i move a window i see it's not smooth and it is slow. In nvidia settings there's only Auto and 60 Hz. If i change it when the compiz still working nothing happens. But if i first close the compiz then change it(whether to 60 or Auto not important)then started the compiz my desktop and windows became very very smooth.
What kind of problem is this? It haunts for long time and i decided to make a search for it.
