First of all Hi,
I saw ur issue here...and registered only to reply you xexe
I am using Ubuntu 9.10 and i had exactly tha same problem. So a possible solution is: to run the commands through a tty window and not through kde or gnome's terminal console window.
Just log off from your graphical environment and switch to e.g. tty1 window with the ctrl+alt+F1 keys. Run all the commands there (after u login ofc) and u are ok.
Switch back to kde/gnome with ctrl+alt+F7
Hope, I helped ya.
