I have an ancient Dell Dimension 2400, with an aftermarket Nvidia Geforce 200 graphics card... I installed 13.04 nd the apps seem to work ok but a bit slow, but the desktop is horribly slow, switching windows, opening and closing ubuntu windows all take forever... I tried downloading the additional drivers, the text in the reviews said "open a terminal and type "$ jockey-kde" but that just got me a command unknown (or whatever)
How can I install the right drivers, or would it be better for me to go back to version 12.04 or 12.10? and if so, how to I make it go back to an earlier version without just performing a full re-install?
thanks
