Linux help

I installed linux last night and i guess i screwed up some setting b/c not it thinks i have a usb mouse and not the generic ps/2 mouse. I can’t use the mouse at all and i don’t know how to do anything with the keyboard

I’m at runlevel 5 in the KDE desktop.

Please help

What distribution? Try reinstalling.

ctrl-shift-f3

login as root

run xf86config and get it right this time
