I installed a LTSP server on top of Kubuntu 16.04 on a PC. The thin client (Asus Eee PC) boots as expected from the network and I get the ldm login screen. I enter my credentials but then I get a black screen during few seconds and it loops back to the login screen. It seems to be unable to start the X session. I used to have LTSP working flawlessly on a 14.04 Kubuntu but i decided to upgrade to 16.04 one week ago...

I spent hours trying to solve it without success.

In the sys log file I found this:

"failed to create session: Unit dbus-org.freedesktop.login1.service not found"

Any idea?

Thank you in advance


After hours of search I found the fix: LDM tries to start by default a session on the server using "gnome-session-fallback". But if you are running KDE (Kubuntu) on the server you don't have gnome installed and it fails. To fix it you have to add a line in the lts.conf file: LDM_SESSION="plasma" I suppose it is a bug I hope it will help some of you.
