I am having the same problems, after upgrading to kde 3.3, my system crashes when I try to logout. Ctrl-alt-backspace, ctrl-alt-F1, ctrl-alt-del not respond, in fact numlock not work, so the keyboard and mouse are not responding. Ping from others machines works but ssh or sftp not. My system: debian sid, kernel 2.4.27-1-k7 athlon XP 2600+ 1Gb ram kdm + kde For now I am using fluxbox instead of kde. Regards, Francisco Vera
