ThinLinc doesn't use the display manager of the system, so changes it to 
it will not affect ThinLinc.

We don't use .xession either. :)
There is a ~/.thinlinc/xstartup which is roughly equivalent. However it 
can be difficult to get right as it overrides a lot of default behaviour 
you probably want. So I would suggest figuring out why the default 
behaviour isn't working.

ThinLinc has the concept of profiles, which is roughly equivalent to the 
session types you have locally on the system. The profile is selected by 
tl-select-profile in xstartup.d/, and executed via tl-run-profile from 
xstartup.default.

The list of profiles is filtered. By default it only removes desktop 
environments it fails to detect, but it can also be configured to filter 
based on users and groups.

I'm afraid the filtering process doesn't log anything.

This is entirely a server thing. The default configuration will look in 
/usr/share/xsessions/ for one of "kde kde-plasma plasma kde4 
1-kde-plasma-standard". What do you have in that directory?
