Install fails on Ubuntu 12.04

As the subject says, I can't seem to install TDE on Ubuntu 12.04. One of the last messages while installing is this: "Setting up kde-guidance-trinity (4:3.5.13-1ubuntu0+ax0~precise) ... Removing any system startup links for /etc/init.d/displayconfig-hwprobe.py ... update-rc.d: warning: kde-guidance-trinity start runlevel arguments (none) do not match LSB Default-Start values (2 3 4 5) update-rc.d: warning: kde-guidance-trinity stop runlevel arguments (none) do not match LSB Default-Stop values (1) usage: update-rc.d [-n] [-f] <basename> remove update-rc.d [-n] <basename> defaults [NN | SS KK] update-rc.d [-n] <basename> start|stop NN runlvl [runlvl] [...] . update-rc.d [-n] <basename> disable|enable [S|2|3|4|5] -n: not really -f: force The disable|enable API is not stable and might change in the future." During install I chose kdm over lightdm. I can login ok, but I still get the Unity desktop. What can I do to rectify this? Thanks for any hints, Mike
