KDE-Trinity 3.5.13 hung my machine

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 As part of upgrading from Debian Lenny to Squeeze, I also upgraded from KDE-Trinity 3.5.12 (Lenny version) to 3.5.13 (Squeeze version). After the upgrade finished, I tried to open Konqueror; the result was a hung machine. - From as virtual terminal (ctrl-alt-F1) I rebooted the machine. On reboot the GUI did not appear; the machine opened with the shell bang. I the logged in as root and ran the command "startx". The result was a solid blue screen at ctrl-alt-F7; further action was impossible. I am at a loss as to what to do next. Specifically what should I do to get the login screen so that I can log in as a user? Ken Heard
