Hi there; A tech friend installed Ubuntu 10.04 on a Dell Pentium 4 desktop computer. (He likes it because it's more like a windows environment and easier to learn than later versions, for a Linux beginner like me.) Anyway when he tries to use the gnome environment, the mouse quits working/goes away. We have no problem with the lighter weight desktop version but of course gnome offers more features. Can you advise what the problem might be, or where to begin searching? Thank you!
