Hi,
Thanks for your answers, i now can connect without problem on the machines I tested.
I have now 2 little problems:
When editing a profile, when I save by ok, x2goClient closes (I have checked all the parameters to hide in notification zone) I use Ubuntu 12.04 and gnome fallback
I have a server (laptop) which have a screen of 1440x900. My desktop computer has two 1280x1024
When I connect to the local session, All the values I tried to have an size with no deformation failed. I tried something like 1200x700, and other values, 1440x900, and it seems it is always the same value, about 1280x930 It's not a big problem, but a little unpleasant
No problem with :50 where the window is about 1280x990, but the screen of the session seems to be created like this, and the background is adapted and no unpleasant modification.
Thanks A+
