My husband's desktop died pretty conclusively at the beginning of teh mirror
outage.  Not knowing about the outage, I set out to install Squeeze + TDE.
Without success, of course.  I tried David's offering, which I liked very
much and had help from several people on this list, but had not succeeded in
getting it all running properly when my husband came home.  So I installed
LXDE so that he could use Thunderbird to read his emails.

He has fallen for the speed of LXDE, and, for once, doesn't mind having to
work differently.  He wants to keep LXDE.

I therefore have a lot of TDE dependencies, but no actual TDE packages.

1) If I install the rest of TDE at this stage, so that it is there if needed,
will it impact at all on LXDE's speed of booting up and shutting down?

I had been intending, as part of the reinstall, to move him from Thunderbird
to KMail. In KMail, it is easier to remove virus-laden emails, before he
sends them on to Windows using friends, without damaging or altering other
emails.  And I know it a lot better, and can more readily answer questions.

2) Would using Kmail slow LXDE down at all?
