I am trying to set up a new computer with Fedora 17 and KDE both working ok. I have plugged in an HP laser USB printer, and am trying to set it up. I enter "system settings -> printers" from the KDE menu, and am asked for a user name and password for authentication. There I get stuck, nothing I can remember gets me any further.
I have no problem with
sudo from the terminal window, nor with the printer on my previous machine with Fedora 12.
Please can anyone help me out of this impasse?
Incidentally, although this is on a dual boot machine, with grub, I have no file
grub.cfg or anything like it.
