Hi!I installed GDM3 3.20.1-1 and now has code to solve this problem, but, in new code, I suspect that has a failure, because the logic in the line 331 should be inverse of original code in 336:
daemon/gdm-server.c:331: if (!server->priv->disable_tcp && ! query_in_arglist) { daemon/gdm-server.c:336: if (server->priv->disable_tcp && ! query_in_arglist) {
I suggest change 331 to: if (!server->priv->disable_tcp || query_in_arglist) { Best regards, Junior Polegato
