[Message part 1 (text/plain, inline)]

Imagine that you have agent window in the middle of two screens. Window
size is 1024x768. You current displays configuration in that case is:
left-512x768, right-512x768. Imagine, that you moved your window 100 px
left. Now your displays configuration is: left-612x768, right-412x768.
But from the view of x2goagent nothing is changed, agent has no idea
about the display geometry on the client side. This is why client
updating xinerama.conf and resizing a window to apply new settings. I
hope it's understandable.

regards,
Alex
