Hey Alex,
As potential (and hacky) workaround you could try delaying the display
manager with a wrapper script like this
#!/bin/sh
sleep 10
${ExecStartCommand}
replace the last line with the actual ExecStart command
if that works, you most likely have a dependency/race/timing problem as
Leon mentioned.
I'm sure there's a more systemdish way to do it (timers?) but I'm not an
expert there and it's a workaround anyway.
No need to do a wrapper script. In systemd service you can achieve the
same using ExecStartPre. Please check systemd documentation for details:
http://www.freedesktop.org/software/systemd/man/systemd.service.html
Best regards,
Leon
cheers,

Hi, Leon,
I did use the same command in the ExecStart element of systemd
service display-manager-run. That is why i am confused.
It might be a race condition with systemd services. I recommend you to
use journalctl to check systemd logs and systemd-analyze to view
system boot-up statistics. Both tools are very convenient for
debugging systemd issues.
Best regards,
Leon
Thanks

Just to clarify: in this case the tizen version is 3.0 and
the profile is called Common.

If you are able to start it manually then just use the same
command and adjust ExecStart of systemd service
display-manager-run.
