This is 100% repeatable on 2 different PCs, one using AMD GPU, the other NVidia GPU, both with only FOSS drivers. When attempt is made to start a Plasma Xorg session from TDM, a window pops up that seems to have come from Trinity, not KDE, but that's just my suspicion. It says General (tab) We are sorry, klauncher closed unexpectedly. You cannot report this error, because klauncher does not provide a bug reporting address.

(try using --replace) Does this suggest where the fault lies, whether something wrong with TDE, or KDE? Is there a possibility this results from a defective switch from Trinity beta from http://download.opensuse.org/repositories/home:/PunisherHD:/Trinity:/stable… on beta Leap to the final Leap and François' build of Trinity? I don't remember if it worked or not in the betas. :( # journalctl -b | grep aile | egrep -v 'plasma|hortc' Jun 11 18:21:56 ara88 systemd[1]: haveged.service: Failed with result 'exit-code'.
