Hello ,
I've the same Issue here , Since upgrade from teamviewer 10 to 11.
I'am on Mageia 4 Linux OS, with kde 4.14 and kdm as login program.
It seems to be a problem between teamviewerd daemon and X11 ( Xorg ) or Kdm.
When i read teamviewer logfile, i can see those messages which can explain why teamviewer does not detect
any "screen" when kdm is displayed.
The logfile is located at : (var/log/teamviewer11 : redhat rpm version )
Here are the corresponding rows :
Here the sequence when TV daemon detect an open session :
2016/10/23 15:16:53.402 26753 4044032832 S XSocket observer: removing XSession: 0

2016/10/23 15:16:53.402 26753 4025482048 S UpdateOnlineState newOnlineValue 1
Here the sequence when, the session is logged out and "KDM" is displayed.
TV daemon doesn't detect any open session :
2016/10/23 15:16:53.501 26753 3960458048 S TerminalServer::SessionLogout for session 0
2016/10/23 15:17:13.758 26753 3960458048 S TerminalServer: XServer respawned, but has no information attached
2016/10/23 15:17:13.758 26753 3960458048 S systemd: skipping update of :0 (ID = c5) as session leader (pid = 2843) seems to be gone already
2016/10/23 15:17:13.758 26753 3960458048 S TerminalServer: XSession did not reappear within 20000 ms, terminating session
An then the teamviewer machine isn't seen "active" anymore on teamviewer interface.
I tried several modifications of kdm and Xserver config files ( Xorg), teamviewer configuration ( with unatended access, wol configured ... )
without any success.
Did anyone here find a solution ?
