I dual boot. I am not a linux guru. I use Kubuntu. My son has vista on his laptop.................I despise it. I installed KDE4 a couple of days ago and have found it to be frustratingly like vista. I can't change wallpaper. Gives some kind of BS error about "orphaned module" or something along those lines. Do I need to remove KDE4 and wait on R1 to come out?
