At the same time My application has to communicate with other session applications, so Iam communicating using session bus.Also My application has to start at boot time by systemd. Is it possible? If possible what are all the changes I have to make?</p> <p>My target board is rcar H3.

Trying to access user sessions from within a system service is somewhat contradictory (is it a system service *or* is it a desktop app?). It *is* technically possible but you need a really good reason as well as to consider that there can be more than one session, less than one session, that sessions can appear and disappear at any time... The only common exception are tightly integrated embedded distros, where exactly one permanent session exists.</div> </div> <div><br> </div> -- <br> <div dir="ltr" class="gmail_signature"> <div dir="ltr">Mantas Mikulėnas</div> </div> </div> </div> </div> <p>=====-----=====-----=====<br> Notice: The information contained in this e-mail<br> message and/or attachments to it may contain <br> confidential or privileged information.
