Mouse works Live but not in HD install.

[Kumagoro]

OK i have searched the forum and found answers but they didnt work

I tried this

sudo mount /dev/hd?? /mnt/hd??
sudo cp /mnt/hd??/etc/X11/XF86Config-4 /mnt/hd??/etc/X11/XF86Config-4.original
sudo cp /etc/X11/XF86Config-4 /mnt/hd??/etc/X11/XF86Config-4

it didnt ask if i want to overwrite so i dont know if it did it or not. I did it as root also same thing
Booted up the HD install nothing changes.

I want to do a copy in paste using Konquerer as it asks if i want to over write but i cant as im not
root. How can i get Konquerer working as root?
