I try the other but it says kedit is not a command and i cant find kedit. so can i do the sam ecode but with kwrite. I tryed the ctrl+alt+f2 and now im in bash screen and i try ctrl+alt+f1-f12 and i cant get back to my other sessions. so what is this sudoers file all about and why does knoppix hate me so much man. lol just jokin. any way thanx soo much for the help so far and i hope to hear more back from you guys.
