Right mouse click the VNC icon on the RPi taskbar then select [Options...] --> [Expert]Bosse_B wrote:Another issue I have found after installing Raspbian PIXEL (latest image) yesterday on an RPi3:
I can access the remote desktop fine from my PC using Real VNC Client and it displays a really nice version of the screen.
However, if I go away for a while (lunch, dinner...) then when I come back the session is gone, vanished...
All that is left is the start screen of VNC Viewer and I have to click the connection icon again to show the remote screen.
Why does this happen? I have not found anything in the VNC Viewer settings that deals with a disconnect timeout or such.
Find IdleTimeout and change the default value (3600 sec) to what you want or enter 0 to disable timeout.
The above can be done either locally or remotely but make sure you are changing settings on the RPi VNC server..... Not the similar settings menus of the remote viewer software via F8.
