ThinLinc can not startk KDE 5 Plasma-Sessions in Version 4.3.0 on ArchLinux. The XDG-Session is called "plasma" and there is a /usr/share/xsessions/plasma.desktop file So you have to update etc/conf.d/profiles.hconf: [/profiles/kde] xdg_session=kde kde-plasma plasma kde4 1-kde-plasma-standard
Fixed in r30112.
Looks good. Closing.
