Actually my /tmp is mapped to tmpfs so I assume it is cleared on each reboot. There should not be any lock surviving a reboot in this configuration. This is why I am so curious on what caused the vt switch - and how to revert it -. The X server shows: $ ps -ef | grep X root 1301 858 2 12:47 tty8 00:02:58 /usr/bin/X -br -nolisten tcp :0 vt8 -auth /var/run/xauth/A:0-uTXGia So X is clearly started with the "vt8" param but I do not know enough about X management to find out which process provides the param. I think I found a hint on what is happening while booting: If I do a [Ctrl]-[Alt]-F7 after a fresh boot while [Ctrl]-[Alt]-F8 shows the login screen, the vt7 shows the Ubuntu Splash screen with the message "Waiting for network for another 60 seconds..." (I do not remember the entire message though) so it looks like TDE tries vt7 first and switches to vt8 because there is something wrong in vt7 (my guess). I have no clue on what could be wrong for vt7 and right for vt8 on the same box! Still searching... midi-pascal
