Disable local screensaver when x2go session is in fullscreen mode about nx-libs

[sunweaver]

I just found that the screensaver gets disabled when nxagent is launched in fullscreen mode:
https://github.com/ArcticaProject/nx-libs/blob/3.6.x/nx-X11/programs/Xserver/hw/nxagent/Screen.c#L1442

However, it may well be that this actually fails.

Furthermore, it is well possible, that the re-enable/re-disable mechanism is not working / not implemented, but should be.

Most aspects of screensaving seem to be broken, see also #263 and #80

I have a fullscreen session. Screenblanking on the native display is disabled (xset q reports a timeout of 0. Activating the screen blanker there by calling xset s 10 results in a blank screen after 10s, and pressing any key unblanks the screen again. I am wondering how the original problem you describe might happen.

I just saw that the local screensaver is disabled in Window.c/nxagentSwitchAllScreens(), too
