[SLVED]xfce refuses to start inside vncserver when launched by systemd

Hey guys,  trying to get a xfce session to start inside of a vncserver instance on bootup.  Running debian stretch with xfce 4.12, and tigervnc

I have created a separate user to run the vnc session, created systemd .service files.  When i run the vncserver command as the user,   it will startup a xfce session just fine.  I can vnc into it and it works.  But when I try to run the exact same command in a systemd service unit,  I always get a vnc error about the X server already running.   But If I comment out the startxfce in the xstartup file for vnc and just add xeyes,  kick the vnc service and vncserver starts up just fine by systemd and will run xeyes no issue.  So I don't _think_ it's a vnc issue. 

Am I missing anything in the environment I should be passing to systemd to get xfce to run inside a vncserver instance at boot?

Re: [SLVED]xfce refuses to start inside vncserver when launched by systemd

Can you post your systemd service file and your vns xstartup file contents?

Personally, I have much more luck running xrdp on the server.

Re: [SLVED]xfce refuses to start inside vncserver when launched by systemd

Hey ToZ,  I think I might have to chalk this up to xfce newbness.  I had included the service file and xstartup in the above code block. 

Whenever we had run kde like this,  it had accepted the & after startkde and I guess kde's session handler took over and didn't terminate the vncserver process.  After removing the & for startxfce4 it worked as it should.

Thanks for the help
